Hello Dr. B. Recently I have a question: if atoms in the 3rd period can accommodate up to 18 electrons, why aren't there elements that have more than 8 electrons in the 3rd shell? Is it because having 8 electrons is the most stable?
Stability is an issue, yes. But elements in Period 3 and below can have more than 8. The d orbitals that start in the 3rd period make it a bit more complicated with the transition metals and elements lower in the Periodic Table. In terms of bonding, it's quite common to have more than an octet, actually. Exceptions to the Octet Rule: th-cam.com/video/Dkj-SMBLQzM/w-d-xo.html
I'm looking at trying to stream Sundays, Tuesdays, and Thursdays. I was planning to do naming chemical compounds but perhaps it would be good to spend some time on electron configs. What do you think?
Hey dr. B could you shoot me a message I’m trying to figure out tritium right now completely just for fun and I need some information on all the isotopes of helium and hydrogen if you’ve got the time
For H this might be helpful: th-cam.com/video/Qtu1hM3535E/w-d-xo.html I actually go to wikipedia - they do a good job with it: en.wikipedia.org/wiki/Isotopes_of_hydrogen en.wikipedia.org/wiki/Isotopes_of_helium
@@wbreslyn if you saw the comment I just made that I deleted ignore it Bc I can’t read at all and I confused titanium for tritium isotopes have always confused me
@@wbreslyn I know now that trit is a isotope of hydrogen and isotopes just mean different numbers of neutrons with the same atomic number (# of p+) but boy was I confused
@@Calebthedopegoat My guess is that the just don't exist long enough to be studied or perhaps they are difficult to make in the first place. We're talking about a half-live of yoctoseconds (ys). That's 10^-24 seconds. That is a extremely small amount of time. It may also that there isn't a compelling reason to research this over other isotopes. Maybe you'll be the person to find that reason!

you have the best videos!! this is always my go to account when i need help with concepts that aren't registering in my mind. thank you so much!
Thanks, that is motivating for me to hear!
Hello Dr.B! It's also nice to see the videos after the streams. Thanks for all the information. Respects.
Thank Kubra! I'm thinking of streaming Sunday, Tuesday, and Thursday. Do you think these are good days to stream?
@@wbreslyn ı think these days are good.
Thanks!
Dr.B,
Thank you the teaching. It really helps me a lot.

hello DR. B, can you tell when the upcoming stream is?? I also have doubts in the spdf config of electrons

Sweet!
Whats the difference between valence shell and valence shell of an ion?
Hello sir can you please teach me how to draw Lewis dot structure for CO
Sure: th-cam.com/video/ZXmJmoV-gcg/w-d-xo.html
Sir please make video on mot VSEPR theory of vot

Good night sir and I am Hamza from India
Good morning! Is Hamza your first name?
@@wbreslyn real name sir and it's my mother's name
Ah, I see. Good to know! I've been calling you Rumana, based on your user name.
