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
