Hey Professor dave, First of all I wanna thank you for your great Videos and I really like the way you explain science Could you please make a video about Abiotic and Biotic factors? Thank you very much 😊
I love your videos so much! Please sir, is there any trick I can use to determine the most stable oxidation state of elements, for example, Mn, without memorizing them?
A common element in LCD screens, which I've assumed was just a plastic sheet? [Indium, as indium-tin oxide] Well, now... perhaps I need to rethink my scrapping, then. Gotta check to see if it's recyclable, now!
I noticed something. The video gives [Kr] 5s2 5p1 for the electron configuration of Indium. But should it not rather be [Kr] 4d10 5s2 5p1 ? Is this an error or is there a reason why professor Dave omits the d and f electrons that get filled while we move over the lower periods of the periodic table ?
It’s because it does oxidize But the aluminum oxide layer actually protects the aluminum from further oxidation unlike iron whose oxide is structurally weak and easily flakes off
Dave, are you insane?!! God damn, somebody can seriuosly hurt! If you mix aluminum oxide with rust, you get thermite - extremely flamable powder. For sapphires cobalt oxide needed
@@ProfessorDaveExplains The abbreviated electron configuration does not involve providing only the valence shell. It involves indicating the occupancy of all shells following the configuration of the noble gas enclosed in square brackets. Therefore, in the case of gallium and indium, electrons from the d-block will appear, and for thallium and nihonium, additionally, electrons from the f-block will also be present. This is important because it explains the occurrence of these elements in unusual (it would seem) oxidation states, resulting, among other things, from the inert-pair effect.
This is one of my favorite professor dave series, I am always looking forward to the next video!
Whole chapter squeezed into 10 minutes. You are appreciated prof
i can't wait until he covers the whole periodic table. this is awesome
Thank you for posting. I look forward to all your other Element Group videos.
grazie professore, guardo sempre i suoi video che mi aiutano con l'università! :)
I'm a materials engineering student and still found this very useful. thanks Professor Dave!
Let him finish the video first🙂
@@badmosh7256 I watched on 2x speed
@@uglycharlie2356 no way dude😂
@@badmosh7256 lol I assumed I would already know everything. I was wrong haha
I just adore this playlist
Who else wants a full version of intro song?
Me hahah
Yes please
Am very happy to hear from you and am proud of you and I will like to learn more about your topic thanks.

wow this video is very comprehensive thanks for what you do.
I love ur intro song a lot …♥️♥️♥️♥️♥️♥️
Great video, we will appreciate more chemistry related videos.
Well explained!
Please explain inorganic all element's polymers.🥺
I love your videos so much!

i wish you were my professor in university
and i wish we studied in english in place of french
First of all I want to thank you for the video that you me and I want you to put more effort. And I will like to learn from you.
This isn’t how we speak on earth. In case any aliens are wondering.
Awesome sir
thank you very much
Any thoughts on Borophene?

What are common properties of "Group 3"?
Could plz answer my question sir
Do plants can feel pain?
No they don't have any nerves or receptors
@@TotallyRat_
If so, how do plants recognize light, water, food?
These elements are called the icosagens.
wow!
Prof. Dave would You expalin why Aluminum is found in nature in oxides but aluminum cans and foil doesn't rust...
Is that becose Aluminum is magical?
It’s because it does oxidize
But the aluminum oxide layer actually protects the aluminum from further oxidation
unlike iron whose oxide is structurally weak and easily flakes off
Pokemon Ruby
Pokemon Sapphire
Pokemon -Emerald- Aluminium Oxide
👍👏
Boron is such a cursed element. All those 3-center bonds.
Also, Gallium should never be allowed to touch aluminium. Makes it weak as paper.
Thallium acts much like an alkali metal in the +1 state even to its reactivity with water, and it is extremely toxic.
Thallium is also sectile. =D

More like "aluminium", am I right?
True! One would think the names of the other elements in the group gives us an idea how to correctly pronounce aluminium as well.
Aluminum, aluminum. They're both the same thing. Do your research!
Aluminum or Aluminium? It's also the same problem with Cesium/Cæsium!
you are critikal
Aluminum*****
Can't say I don't like molten boron.
Does anyone else suddenly want a boron inspired d20? Just me? Ok.

Wrong electron configuration
no
@@ProfessorDaveExplains what about d and f block?
@@blueseven9420 only the valence shell is listed
