As someone who had to learn this way before these existed and had a Professor who was only reading everything from the PowerPoint without even trying to make it sound interesting you better use Prof Daves Videos! As a Food Chemist i ve mostlyno use for a lot of what is said in these inorganic videos yet i enjoy them a lot
@@borysnijinski331 Really? You should know the allotropes and compounds for every single element along with all of its natural sources and human uses? I don't think that expectation is reasonable for an undergrad. I doubt even a fully fledged chemist would "already know all of this" lol
I have a few suggestions or questions if you'll ever do them. I cant wait to watch this playlist when I'm studying chemistry. Will you ever do: Euclidean construction Engineering Computer science Coding Thanks dave Btw not pressuring I'm just curious if you will since you already have enough work to do with geology and such
Trying to get a like & comment on all of these as I go through the playlist, for the Almighty Algorithm! Learning a lot of interesting stuff, which makes me happy!
Arsenic and antimony allied with copper where used to make bronze over 2200 years ago. In the ancient times, it often caused deformities among blacksmiths.

i think we have reach a point of development that it most likely doesn't matter which path we take it will cause some permanent changes to the earth . i think we should change the way we try to solve these problem , stop always trying to go back to the way the environment was , and try to create a new , even potentially better environment . in a way we are crazy, in the sense that we view re-engineering the planet as some kind of crime , even if it is essential to our survival .
Sounds like the more Advanced Technological world we live in, the quicker we use up these things. No worries.The OneEyedFarmers will take care of us 👁🚜💰🤣
Great discussion of Group 15, Professor Dave! One additional comment on nitrogen and phosphorus that I think people should know. These are the two "nutrients of concern" for virtually every advanced wastewater treatment plant in world. Left untreated, these two nutrients can (and have) seriously impacted plant and marine life in streams and rivers. For the same reasons these elements make good fertilizer, they also, unfortunately, promote the growth of algae which, left unchecked, can smother a water body, preventing the penetration of sunlight, and causing eutrophication in water bodies. The next time you complain about your sewer bill, realize that a good chunk of that money is being used to remove nitrogen and phosphorus from the waste stream. See oceanservice.noaa.gov/facts/eutrophication.html if readers are interested in more information on this important aspect of nitrogen and phosphorus in our natural environment.
Going to University for Chemistry so these videos have given me a head start

If you are going to university for some STEM course that includes chemistry, you should already know all of this.
@@borysnijinski331 i sorta did but it was a refresher

Bro I’m in it and haven’t used the is yet but probably will soon
2:53 220 ms thats like a match lighting up the red P then to burnt p(p = phosphorus)
Antimony is also mixed with tin and copper and sometimes lead to make Babbitt metal for bearings
I have a few suggestions or questions if you'll ever do them. I cant wait to watch this playlist when I'm studying chemistry.
Will you ever do:
Euclidean construction
Engineering
Computer science
Coding
Thanks dave

Arsenic is often used in the lead grids of lead-acid batteries to harden the lead and prevent deformation during manufacture and operation.
No, that's antimony that's used in lead acid battery plates
WOW! Great as usual, I actually study group 15 elements in chemistry, garde 10 Egypt!

Group 15 should be called the boring group

Non-lead ammo on shotguns and weights of fishing rods are often bismuth or it's alloys.
Under extreme pressure and heat a solid nitrogen allotrope analogous to black phosphorous ha recently been synthesized.
i know bismuth for its beauty
Thank you ❤️
Interesting stuff
Nitrogen also has +2 and +4
And arsenic could have -3
so awesome
Plz make a playlist on periodic table.plz
Thank you so much for your Videos.
Dearest Professor,
Do you know enough about systems chemistry to make a video on it?
It would make me very happy.
Much Love,
TH-cam person
Maybe I’ll hire someone!
Beautiful 😍
Ahem cuzinz 🏵🧙♂️👍

Hard to overstate how necessary nitrogen and phosphorus are for complex life.
Thanks
Nitrogen does have another allotrope! Look up black nitrogen
Can you do a video about group 16 17 as well
As far as i understood his introduction to inorganic chemistry he said he will do a video to all groups
Love it!
I thought nitrogen has more than one allotrope, such as the allotrope black nitrogen.
Would Tiberium fall in this group?
Are these truly located mostly in China or is it that China just does most of mining of these?

😊👏
Professor Dave is there a way for me to email or contact you regarding something I believe to be important?
Email in description
It’s group 5 not 15 - sorry not sorry but I’m a welsh chemist 😂
It’s not often you hear the welsh being humorous. Yep, it’s a welsh rare bit.
Huh? Group 5 begins with Vanadium, right?
@@glennpearson9348 group 5 is nitrogen, if you’re a proper chemist 😂
It's both right. The 5th main-group elements are beginning with Nitrogen but the proper modern groups are the IUPAC-groups which is the 15th.
@@TotallyRat_ nevvvvverrrr!!! 😆
well. least the meth industry will be out of business when the phosphorus is mined out

I'm happy to pay my sewer bill. It's fairly inexpensive in my area.. Do some people have really high sewer bills?
@@SoulDelSol It varies. Pretty wildly in some cases.
