Back in 60's when I was a kid (around 10 years old), my friends and I would ride our bikes to the drug store and buy bottles of ammonium dichromate. Big bottles of the stuff. After a few purchases, the pharmacist finally asked, “what in the world are you kids doing with all this ammonium dichromate anyway?” Oh, we're just making ammonium dichromate volcanos in our back yard. The pharmacist shrugged his shoulders, looked at us directly and warned us to be careful. We were careful and no one got hurt. And that how things went back the day for kids from Lake Wobegon.

Yea, The pharmacist that owned the pharmacy I did my residency at talked about all the cool things you used to be able to do. Mostly explosives. Until they cracked a window with their black powder, and his mum put a stop to it. We used to do random chemistry 'recipes' from the 18th century 'useful household things' ranging from fireworks to glue to pesticides.

Dichromate and Chromate (chrome 6) salts are also pretty toxic and highly carcinogenic. Just saying, probably not a bad thing that kids can't buy a drum of it from the corner store.

I could certainly use that video. I've been educated to a small extent on the elements and how they tend to generally react in the broad scope. I want to know what makes these sections of the table unique.
@SpritoftheStairwell
@SpritoftheStairwell 6 жыл бұрын
The simplest answer to why they are arranged in such a way is the valence shells of the elements. The s-block (groups I and II) have s-orbitals as their valence (outermost) shells, the p-block (main group) elements have p-orbitals as their valence shell, and transition metals have d-orbitals as their valence shells. The number of electrons that can go into the d-orbitals and their various energy levels are what cause them to have unique reactivity.

You don't really learn anything from these videos. You have to have a basic understanding of whats going on to understand the reactions, enough to where you wouldn't be learning anything new, you'd just be seeing something happen that you already know will happen. If you don't know enough to understand the reactions, you won't know it from watching the video considering nothing about it is actually mentioned as these are beginner oriented novelty videos not educational videos, you'd need to spend a long time studying reaction pathways in an actual classroom before it could make any real sense.

Professor, two weeks ago I witnessed the brightest meteor I've ever seen. So intense that I cast a dim shadow as it passed. It was the most amazing pale green. I know this might be more of a astrophyisics question, but I wondered what chemical makeup would show a color like that. Another factor was that it looked like it just skipped off the upper atmosphere, so maybe it was burning yellow and was "greened"" though our blue tinged atmosphere, so green and yellow could have been the real colors as it burned.

The reaction at 6:30 forms a violet peroxo complex of chromium, thought to be [CrO(O2)2(OH)]- if I recall correctly, not two different compounds as stated. This then decomposes to oxygen gas and is reduced to green Cr(III). The peroxo complexes of chromium are awesome and you should make a video dedicated to them in the future!

I subscribe to the entire BradyNet, but back only Sixty Symbols. I'd really like there to be a BradyNet Patreon so I can more easily support all of Brady's work.

BobC I think it's best the way it is, he can see how channels are doing and allow people to support specific shows It is probably more profitable too.

I'm certain BradyNet is already sentient. I'm more worried about what will happen when *I* become sentient!

The Prof makes a brief mention of not being allowed to do things these days...I absolutely DESPISE that we have lost so much freedom in that respect, back in those days ...man I wish I was around back then...I know to them at the time it wouldn't probably seem like such a big deal, but they had freedoms that we can only dream of nowadays.....

With the later noble gases, the electrons are too far away from the core, so oxygen and fluorine are strong enough to steal them.

2:48 Remember guys: Do not put the oxide into the acid. Put the acid onto the oxide. It's a lot more dangerous to put oxide into acid than acid onto oxide.

I was hoping that the Professor would say some comments on the powerful halucinogenic drug Adrenochrome invented by Hunter S Thompson.
