"yeah man it's right above [Xe] 4f^14^ 5d^10^ 6s^1^, you can't miss it"

Hey look, it's a kürzlich aufgebauter vom Aufbauprinzip verbauter Bau

Edit: also, the configuration is referring to silver for those curious. Not my first choice, but whatever floats OP's boat (Baute?) I suppose.

Ag, just circle the damn room for me!

Arsenic? Did I count right?

~~31 electrons if I can count, so Gallium?~~

~~Although I'm pretty sure that electron configuration is made up~~

Edit: nvm, see comment below, 47 electrons is right, been a long time since I last did chemistry :P

Tf guys i count 47 which is way above 31&33.

How are you guys counting?

[–] mexicancartel@lemmy.dbzer0.com 12 points 2 days ago (1 children)

Which is Ag, consistent with s1 d10 format

It's been over 20 years, but why is 5s1 4d10 a correct representation and not 5s2 4d9?

Edit: is it because d10 is more stable than d9? But then s1 is less stable than s2.

Half and full filled configurations are more stable. s1 is still half filled and d10 is full filled. The net effect it better stability even if s became a little less stable

You're right, according to online calcs. But man I can't remember how to count these myself.

Wanna explain for someone who didn't have to do much chemistry?

Add up the superscript numbers. That gives electrons, i.e, atomic numbers.

I'm a musician I count by ear

It's silver

[–] callyral@pawb.social 13 points 2 days ago (1 children)

i dont understand this, what kind of polynomial is that

[–] henfredemars@infosec.pub 41 points 2 days ago

It’s an electron orbital description of an element.
