Holmium - Periodic Table of Videos 

_"Languid centaurs praise Ned's promise (of) small european garden tubs. Dinosaurs hobble erratically thrumming yellow lutes"_ ...where can I buy Sir Martyn's brand of _green tea?_

Oddly enough I just use the element names as a mnemonic to remember "Languid centaurs praise Ned's promise (of) small european garden tubs. Dinosaurs hobble erratically thrumming yellow lutes"

The "holm" in Stockholm means a small island. It's not very common in English anymore but still remains in Nordic languages like Swedish. The "stock" part is either stock (log, stake, pole) or stäk (apparently old word for bay)

It certainly has the most gangster abbreviation.

You need to do like a top 5 most underused elements!!!

Hypobromite before Holmium

This channel rarely uploads videos in comparison to other channels I watch and I like that, because these videos have a lot of effort put into them and their brilliant - (and Brady also has a lot on his hands). Just trying to clarify that this comment so far is not meant to be percieved as offensive, but quite the opposite. And when I see that a video has been uploaded, I get really *really* excited and get some popcorn, and I love it. Thank you for making these videos.

where the hos at

Glorius HD quality, just what the channel needs, love it!

I simply love the periodic table of videos !

That is quite a long Mnemonic to remember for the Lanthanides.

This episode for me is in the top 3 of all of your videos I have watched. Great solid science discussion. Thanks especially for the odd/even Helium piece! Both Professors are the cat's meow.

For HPLC UV detectors (DAD or VDW or MWD) Holmium filters are still used for calibration. So it's still quite important.

Father Christmas adores Tri Holmium, Ho Ho Ho. (And keep your new Holmium with you for a better holiday).

I don't know chemistry that well but it sure is interesting that when you review Holmium's characteristic traits it seems like it could be a major component of a neutron star. It absorb neutrons and has the highest magnetic moment of any other element. Also, I learned that Holmium has a half life of 1200 years because of it's high spin. Also, it;s high excitation rate produces gamma rays in the decay process. There are so many characteristic traits of Holmium that make me think of a neutron star/black hole. It most certainly SHOULD NOT be the forgotten element, otherwise, we will be in spiral straits.

Things I love about my casual interest in chemistry: Waking up to a video which says “Ho”😂

Ned's promise... Like "Promise me, Ned?"

Holmium pole pieces are used in MRI machines, in which extremely intense magnetic fields nuclear spins can be measured.

I think you might of forgot the coolest thing about holmium. The way it changes color in the spectrum of visible light it's in blows my mind every time I see it.

8:06 stunning to learn

6:16 Holmium is my spirit animal.

That odd/ even thing - amazing, and obvious once you know it.

For those interested, a Dutch company uses radioactive holmium isotopes in microspheres to treat unresectable liver cancer.

Please make an updated Thorium video! Thanks!

The detail and specificity are really nice. Please do more!

You're a genius sir. Your students are blessed to be taught by you.

Damn shame the atomic number for Ho wasn't 69. 😔

Im getting some holmium cant wait for it. its interesting how the lathinds electron configuration is very unormal and that there compounds are not very stable as they can decompose quite easly apart from neodymium and iron (neodymium magnets)

1:18 actually, I decided to memorize the whole periodic table. I'm currently in 110 8 more to go actually, 17, if you consider some of them, that don't hava a fixed name.

Would be great to see a video about THC. To get some facts from someone who really knows what they are talking about. Love the videos! :)

I'd really like to see a video about the molecule on the cover of the Nature Chemistry journal. I believe it was the facially polarized hexafluorocyclohexane molecule that was recently synthesized. It was an interesting challenge that produced a very unusual molecule - definitely worthy of some attention.

what's Santas new favorite element? Holmium Holmium Holmium

7:07 You got mail!

Am I the only one who feels a strong connection to Holmium after hearing how rare and antisocial it is?

I think that Gd is a true neutron eater. When it comes to abundance of odd isotopes it's more about the pairing energy because nucleons prefer to have a couple. Other factor which makes some nuclei more abundant is the shell energy. Similar to electrons you can quantize nucleons in a potential (but created by themselves) and you get different orbitals and shells. When the shell is full you have a magical nucleus. Still love you guys!

I would say that Gadolinium is perhaps the more familiar neutron absorber than Holmium.

Thinking that would make magnets for great extreme cold electric motor.

I had to make an advertisement for holmium for a school project, and we needed to make a slogan for the element. I chose it so I could write the word "ho" in giant letters on my paper. For my slogan I wrote: "An element not just for show, meet the wonderful magnetic ho!" Best project ever.

I think I'll never outgrow laughing at the element "Ho"

lots of interesting facts! and honestly, i hadn't even heard of Holmium before

Is that a periodic table clock in the background? :D

Fascinating and well presented to boot. Thanks, Brady.

Really happy about this update, another excellent video!

0:56 my mind has been forever altered by the imagery of this acronym

Nice element. I bought a kilo of it along with a kilo of dysprosium about two weeks ago. I am in the process of making a lanthanide periodic table made out of real lanthanides - and in no less than 1/2 kg amounts per element. Photos on request!

1:26 you sir are a genius!

Never heard of a mnemonic for the lanthanide (or any other) series

Thank-you, Martyn. _Languid Centaurs Praise Ned Promising Small European Garden Tubs; Dynosaurs Hobble Erratically Thrumming Yellow Lutes_ is even easier. Any better ideas for Yb?

Man, this channel is so freaking cool

Temperature adjustable magnetism sounds like quite useful property

Yup repaired a few holmium lasers. The lasing rods are very deep green because they are doped with chromium and thulium as well as holmium. This allows the lasing rod to operate near room temperature 🤓

Can us 'Periodic Videos' fans be referred to as "Periodicals?"

Thanks for doing my video request!

Dear men of chemical circles, Holmium laser is THE best thing for kidney stone destruction and for removal of large benign prostates. These are the instances where a watery surrounding of operative field prevents the effective use of many other modes of surgical laser/coutery. I'm glad non of you has met any of my colleagues as yet ;) Wish you all stay healthy!

on September 24 the LHC(Large Hadron Collider) Zern(Switzerland) will maybe create new elements.if everything goes well

Why is the stretch of elements between somewhere around Mo to Nd flipped? is there a radioactive element that forces an even element to be rare, and that got carried on?

You need to do a video on learning the elements of the table, not just the first row f

What property does it have when it's dirty?

6:00 So, obviously, it's not the valence electrons creating the spectrum, it has to be the unpaired electrons in other shells.

Bros before Ho ...had to be done

How come on the graph Samarium and Ruthenium seemed to break the up-down pattern? So did lithium and boron

Thanks for the video.

Can't wait to get a t-shirt with this element on it!

strong magnetism at low temperatures... damn that instantly boosts my imagination for my next pen and paper session :D

funny that stephen says lanthanides dont change much. i did research that was based on them changing depending on whats bound to them! :)

so which element does the professor think IS the most underused? maybe a short list of the 5 most underused?

How do remember the actinides?

Finally new video! Thanks!

Love your videos. Thank you!

My favourite.Derived from the word Stockholm.

1:14 I loved that

next schrodinger equation plzzz..

1:24 The students say" Wow! You're a genius!" Ummm yeah... You're a genius.

I helped to develop technology to use holmium in multiple myeloma. It's useful in cancer therapy

Where can I purchase the Periodic Table tie worn by Sir Martyn?

might be a silly question but is Holmium reactive with other elements? such as the reaction you find with aluminum and mercury or even fluorine with just about anything.

Yb=yellow?

,How many elements are named after something swedish? I'm absolutely loving it.

who thought of Sherlock Holmes at first ?

In what universe is that mnemonic easier to remember than the literal names of the lanthanides?

Did ecology that was all about environment. So was chemistry ie solvation fx. Even nuclear magnetic resonance spectroscopy involved the environment around the hydrogen atoms. Interesting that spectrographic analysis of rare earths reveal little difference when comparing the isolated element to the element bonded to an unlike atom.

It feels good to be back on the sunny side of RU-vid. I just spent a few hours watching the darker side. Lists of serial killers, horrible accidents and the like. Why do I keep doing that to myself?? Especially on late nights when the weather is bad and I'm home alone. Only 3 hours till dawn...

Is this guy related to the host? He seems to be wanting to emulate Mr. Periodic.

I have one Mine of rare hearts elements in Brasil. "Monazit".

My takeaway: Beryllium: Very light element. Even atomic number. Super rare. I'm kinda surprised they made no mention of that obvious outlier.

dude is such fun teacher!!!🤣🤣🤣👍👍👍

In order for me to remember organic chemistry for high school, all I had to remember was Nonane and Decane. Before that, it went thusly: Many Eons Passed Before People Had Hairy Oranges.

I would swear that when The Professor is talking about Holmium laser, you can see the electrical blueprint flashing past his eyes. o-0

Sherlock Holmium: it’s elementary.

I wonder what the least useful (stable) element would be.

Aren't you already a genius, Sir Martyn?

The beauty of the heavier elements is that when they’re boring they’re boring small but when they’re exciting they’re exciting big

Those are some Dank protons.

Hmm, so there's quite a few elements that have names that relate to Sweden, it seems? Strange for such a small (by population) country.

I really like this video.

Show us a sample.

why is Promethium not on that abundance chart?

Mr Bean's Prof. brother has more information under that hair than Google.

What ever happened to Pete?

I'm disappointed by the explanation (at 7:40) of the relative abundance of elements, the kinematic explanation about even and odd nuclei is incorrect. The relative abundance is an effect of nuclear binding energy and similar spin pairing dynamics for the protons as those of electrons. Protons and neutrons can spontaneously change into each other in nuclear reactions so that proton number is not conserved odd p + odd p = odd p + neutron+ positron is an allowable reaction (for example Hydrogen + Hydrogen = Deuterium + positron + neutrino). Please consult a physicist when discussing nuclear reactions.
