Copper - Periodic Table of Videos 

The dude in green analyzing the grade A copper wire was talking so quiet. Atleast to me. He's like, "Its so majestic. We speak softly so we don't disturb it."

The prof is just such a fantastic story teller. I thought the running after a crab vs. a rabbit story was genius.

Niel's wink though... ;___;

Now I can't help but picture the Professor chasing a lobster.

They didn't put copper around the tops of buildings because it's pretty, although it is. When architectural copper gets rained on, copper atoms will wash down the wall...killing all the algae that tries to grow on the building. Shingles sold today have copper in them for the same reason.

Mr Neil is really weird. He's like that second plan hero, who often is more intresting than the main charachters.

My mom used to tell me before bedtime or when I felt overstrained, that there's always and ever a Neil behind me, twinkling and taking care.

You know you have a special wife when you can give her a copper ball for christmas and she'll be happy. :D

"Hey Vinnie, and what if the coppers show up while we are, y'now, at work?" "Don't worry about it, Tony. Coppers have this blue blood, this hemocyanine thing, and they tire real quick, so you just keep running."

Why is Neil such a beast?

I'm gonna go chase down some lobsters on the beach and see how quickly they get tired now. :D

2:09

This video would have been vastly improved by some footage of the Professor chasing after a crab. Show, don't tell!

i immediately fell in love after neil winked at me

We used to fire the TOW anti tank missile on the range at Camp Grayling. Each missile has two hair thin copper wires that trail behind it all the way to its target up to 3600 meters away. The warhead of the missile has 2 copper cones with explosives around them.(shape charges). When the charges explode. The copper cones melt and are projected through the metal armor of the tank in the form of a copper rod.

Having watched several of these "Periodic Videos" I can say, with a strong level of consistency, chemists are a special breed. Like so many Latin students or members of marching band there is a distinct peak and valley for every individual on the electron spectrometer. Still this has to be one of the most underrated channels on YT. I love it !!

"I like to collect shite...shiny things! Pretty things. Here's my copper." haha good save ;)

Pun 29 I now have a copper pun, and I'll tell you all about it when I Cu again. That wasn't just a pun, also a song reference. Oh my.

My self esteem has been significantly improved by knowing I can easily outrun a lobster. 👍

I melted when Niel winked

Way to go man... to few people are as nice as this on the internet.

I've been binge watching these videos this weekend, and enjoying them quite a bit. I've noticed is that everyone has a slightly different accent. Since I'm from the US I can't tell which region of the UK they're associated with, only that they are different. But they seem a bit more pronounced than US regional differences, although I could simply be used to US accents.

oh how I do LOVE these genuinely educational videos! And that professor is just... SO ... EXACTLY what you think of, when you imagine a university professor XD he fits it so well!

Well done, as usual. I am using these videos to help me review chemistry as I change vocations. Thank you.

Meeting the professor is near the top of my bucket list! :D

Amazing. I remember watching this video in high school and falling in love with chemistry. Now I'm in the fourth year of my chemistry degree and going to write a research paper all about copper this semester. fun!

Love these side-stories like about lobsters and rabbits, make the theories come alive.

Copper power cables are becoming a thing of the past for trains here. People simply cut it down and steal it, disrupting traffic badly. Also... what makes Vulcan blood green then if it isn't copper? ;P

ewkay, so COPAH very very very nice sample of very fine copah whyAH

@TreVelocita It's a magnet underneath the plate. The rod is made of conformal-coated iron.

I just really like the color of copper in solution. I've also seen it turn darker blue when mixed with a base like sodium hydroxide, which precipitates copper hydroxide.

"he knows what i'm like, he knows i like to collect shi..."

I absolutely love this channel, I learn way more from it than i do even in my HS chem class >_

I think getting a wink from Neil just made my day.

Can I go with you to a high school? The looks on the students faces would be priceless when you get excited about showing them copper wire.

Just excellent. I keep learning new things here.

4:32 the very last part of the Stone Age, prior to the introduction of bronze, is known as the “chalcolithic” period. That was when people started making use of copper metal deposits that they came across for tools etc. Of course, the softness of copper limited its use in this way. Then smelting of copper from ores was discovered, as well as how to mix it with tin to make bronze, which was a much harder metal. (Not as hard as iron--that came later.)

Chemistry is amazing.

@paronfisk There are actually guided tours down into the mine as well. I don't remember if you could see the tree but I remember hearing about it.

Neil is the actually genius behind everything. Heisenberg *cough cough*

@FUGGINGMAD I believe it is a magnetic stirring bar coated in some hard plastic. You can find much info about it on the web but in essence what happens is that you create a rotating magnetic field under the magnetic bar (inside the base of the device) and this makes the bar spin and then of course use this stirring motion to help dilute your solution.

This chanel is better than having a class

@McPrfctday it is magnetized iron or some other magnetic metal (it has to be effected by magnetic fields), and the plate the beaker is sitting on generates a rotating magnetic field that pushes it around without direct contact. It's an analog to induction heating. The same principle is used in electric motors.

I was too busy looking at the zipper earrings

we need to recycle our rare earth metals much better than we do right now, especially with those which we need in the semiconductor industry are generally needed for Building electronics. Some of them like Cadmium are extremely rare from the start and are getting wasted in throw-away products like batterys. But i saw another video on the topic of recycling electronics to recover the precious metals which looked pretty much as we are indeed making progress; just needs to be kept in mind by everyone.

"so if you start running after a crab or lobster, it quickly gets tired, compared to running after a rabbit or something" lollll this guy always cracks me up

Gotta love the Professor's analogies

@HerrCameron the stirrer is magnetic and the metal thing beneath it uses a current to spin it

Best youtube channel ever!

I love these videos

Wilson's disease.. ah yes. the only actual medicine I ever learned from ''Scrubs'' :).. and I LOVE the colour change to cuprous oxide.. childish of me perhaps, but just beautiful. Really enjoying your videos, subscribed and slowly making my way through them. I mentioned the series to my son, who is home schooled.. and of course he already knew and was subscribed. Good lad!

I love this channel. I've always thought that Copper reacted with Oxygen and the Green was just oxidation I would have never known its the Co2 that is causing the reaction.

Prof Neil's wink is legendary🔥

This use of sodium potassium bitartarate is great. As an afterthought. Maybe a video on the Solvay process would be nice to do. I think it would help to actually see it in action. Then maybe a video on cream of tartar or the crystal in jams and wines could be done to show potassium bitartarate.

@McPrfctday There is a magnet in the heating pad. One knob controls the temperature, and the other controls the spin of the stirring bar.

@BecuzIt No, it's only coated with a thin layer of copper.

@McPrfctday I believe the bar is like a metal that can be magnetised(iron) and there is a magnet spinning under the beaker.

@McPrfctday The heating plate has a rotating bar under the surface and the stirring stick is a magnet, or the other way around. Thus when the bar turns, the magnet follows the turning bar and hence stirs!

The crystal covered apartment that the professor talked about was done by Roger Hiorns and the work was titled SEIZURE. There is a small Wikipedia article about him, several low quality videos touring the apartment on RU-vid, and a descent video of the artist at the site explaining the process and the art itself on Vimeo titled "Artist on site: Roger Hiorns on Seizure" [7184407].

What was the reagent added to change it back to the copper II blue color? Also, if possible, what were the quantities/concentrations? Thanks!

@Serostern This is true, electrical wire is in the high 90s though. But still, there was some kind of legal thing about copper brake pipes, hence the alloy.

Wilson's Disease is actually a fairly common disorder as genetic disorders go. I have a few family members with it, and I have the fairly descriptive Kaiser-Flescher rings but very few other symptoms of the disease. Copper really is shockingly involved in biological life

Kennecott’s Bingham Canyon Mine is the largest man-made excavation in the world, and is visible with the naked eye from space. 0.6 miles (0.97 km) deep, No we don't have to dig deeper. While mines in Chile have over taken the Bingham's production leadership that mine alone provides about 13-18% percent of the U.S.'s copper needs. One mine. worlds largest consumer up to 18% each year from a surface deposit. P.S. the amount of gold and silver pulled out of the mine is greater than the Comstock Lode, Klondike, and California gold rush mining regions combined. And it doesn't show signs of ending the vain till after 2030.... just sayn'

Não sabia que usam um composto, chamado composto azul, e que o cobre serve para outras utilidades como por exemplo uma panela cozinha

that is in fact,a very nice question!copper sulphate,in water disassociates into cu2+ and s04- ions.now,cu2+ ions is what gives it the blue color.normally,copper metal is red because it absorbs colors of higher frequency like green and blue and reflects the reddish colors.however,when it is ion(cu2+),it has less electrons.this changes its electronic configuration,and thus it now absorbs lower frequencies like red and reflects higher frequencies like blue.

Physics of the stirring bar!!! Needed!

@McPrfctday I think it works because there is a magnet in the hotplate that spins the metal bar

The horseshoe crabs blue blood is harvested (thankfully without endangering the crabs) by the pharmaceutical industry, because it works as bacterial contamination indicator. Thanks for the video...

At a restaurant, one person asked for H2O. Another person sees him order water so he says, 'I'll have some H2O too.' (H2O2) After that, the second person had a terrible day.

@1RadicalOne Everythings toxic in the right quantity and /or form. Which bit were u referring to?

02:09 dat swag

You should visit Vienna. We just love our green roofs: Karlskirche, the opera, our parliament, the Belvedere...I can't imagine the roofs to be in any other color.

3:18 yoooo I remember reading through that blue book behind you when I was little the memoriessssssss

What was the solution you used to reduce the Cu(i) back to Cu(ii)?

I love watch youre video PERIODIC VIDEOS !!

I watch Periodic Videos for Neil.

Thank you for using metric units. It really means a lot, and I'm not even being sarcastic.

I love the Periodic Table bow tie!

@sjcwoor Copper(II)- oxide is indeed orange, while copper(I)- oxide is black. The green color on statues comes from copper(II)- carbonate, which is formed when copper reacts with the carbon dioxide from the air.

@onlyreallifematters Plutonium is actually fairly harmless unless it enters the body. So, as long as you washed your hands afterwards, you should be just fine... Unless you were talking about the weight of the plutonium making you not want to toss it around.

That bow tie is perfect professor!

what did you add to reverse the reaction?

Requesting one on Copper Sulfate, used widely during my chemistry classes at school, no idea what it does or what it's for or why it's used at the early stages of teaching chemistry.

Brady, could you add captions saying what materials are mentioned? I'd add the equations as well, but some people might get deterred by those :)

how is there not a science cartoon for kids starring all these adorable nerds, going on chemistry adventures

One of my favorite element

@Tetraglot no - Copper(I) oxide, Cu2O. Copper(II) oxide is just bog-standard copper oxide :)

What did she add to the solution to reverse the reaction?

I am glad you feel that way.

anyone notice from 7:22 to 7:54 the words on the screensaver to the left of him are switching between two different coputer screens?

My work takes me to alots of greenhouses. They have drinking water fountains. I noticed on one of them that read "Antimicrobial copper". What makes copper antimicrobial? Any special process?

Is that ball the same ball in the book,The Elements by Theodore Grey?

For hundreds of thousands of years, in the Stone Age, humans relied on sharpened stones to make tools. But about 7,000 years ago, we discovered how to use copper! And that was pretty much it for the Stone Age... Copper tools were soon the thing. They looked fabulous, but they were just a little bit soft. Then people realized you could add tin to copper to make tough bronze. Bronze was amazing for making anything from swords to cooking pots. The Bronze Age began about 5,000 years ago and we've been a metal crowd ever since. Bronze isn't used much nowadays-- iron is much cheaper and easier to make and even stronger. But copper's making a comeback! Only silver conducts electricity as well, so our electrical wiring is made from copper.

Two graphite pencil leads, copper sulfate, a nine volt battery, and two wires, you can make copper flakes to precipitate on one of the pencil leads. I think oxygen gas bubbles off the other electrode.

The Prof has invented a new sport - lobster chasing

4:55 WE NEED TO GO DEEPER.

Great video

Crustaceans use haemocyanin to transport oxygen because it can hold onto the oxygen more tightly than haemoglobin, preventing it from bubbling out at high pressures. Some divers experience an effect where the oxygen bubbles out of their blood (they use higher concentrations in the breathing mix) which can cause serious issues. I'm pretty sure haemocyanin has 4 times the affinity for oxygen, but this means it is transported and cycled much less slowly, thus wearing out the organism quicker.

What concentrations for the CuSO4and tartrate solutions?

That wink killed me.
