If I had a teacher like this guy, I may very well have gone into chemistry instead of Mechanical Design. All teachers should have the love of a subject like him.

Now I use it for Plating, metals finishing, pyrotechnics, gardening, etc. So many things that interest me ended up tied to chemistry.

1:26 Translation: About the Element with the atomic number 61 by Luigi Rolla and Lorenzo Fernandes The search for the yet unknown elements of the 5th period that, according to Moseley's studies have the atomic numbers 61 and 72, has received attention in the last decade. The Problem about the former element (note: Maybe they meant "latter") has been solved in the year 1923 by Coster and Hevery by the discovery of Hafnium. The Element 61 though is not yet discovered.

@TheKnaeckebrot 6 лет назад

i was wondering why italian scientists published in german? :D maybe soth-tyrols?

@illuminati.official 6 лет назад

Germany was sort of the center of the scientific world until the Nazis decided they didn't _want_ to be the center of the scientific world if it meant admitting that most of their best science was done by Jews. The Americans and Brits decided they didn't care as much and were happy to take over leadership in science if Germany was done with it. The standard language of science has been English ever since.

Why is this atom and Tc so unstable?

@mossy8419 Месяц назад

No isotopes of Tc or Pm are beta-stable, which means that there are no isotopes for which the number of neutrons prevents neutrons decaying into protons or protons decaying into neutrons

@asheep7797 28 дней назад

They're pretty odd, and their neighbours are stealing the stable isotopes from their isobars.* *the explanation is not this simple

The promethium battery is a cool idea, and I seem to recall someone tried to make a similar battery out of tritium. Was that Nurd Rage? The other thing I was thinking is that phosphors aren't just for old TVs; most of the modern LEDs produce blue or ultraviolet light and then use phosphors to give white light and other colours.

@RedwoodRhiadra 6 лет назад

Yes, that was NurdRage who made the tritium->phosphor->photocell battery.

@christmassnow3465 4 года назад

I like to watch the videos on the elements. One thing I hear often is about the predicted properties of yet undiscovered elements missing in the periodic table. Make a video on the heavier elements beyond the 100 elements: what is the highest atomic number for which current science can predict its properties? What do we expect to find at the "island of stability"? Is there a stable element with a higher atomic number?
