Arsenic? Did I count right?

31 electrons if I can count, so Gallium?Although I'm pretty sure that electron configuration is made upEdit: 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?

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
