Ag+ Configuration

Postby Jordan_Wesson_2J » Tue Oct 30, 2018 9:28 pm

Why is the electron configuration for Ag+ 4d10 instead of 4d9 5s1?

Hello,
I believe it is taken out of the s orbital because it is the outermost shell and would require the least amount of energy.

It's because the electron is taken from the outermost shell, which would be 5s orbital, leaving 4d^10 which since it is a full shell, is stable.

Ag has the electron configuration has [Kr] 4d10 5s1 when you take one electron out of the shell it comes from the highest energy which is 5s shell and it is also more stable to have the full d shell than a full s shell.

An electron configuration with a full (or half full) 4d-orbital is more stable than a partially filled 4d-orbital.

I think Ag is like an exception, where you remove one electron from the s orbital and it makes the d orbital full, so d10. Cu (copper) and Cr (chromium) follow the same pattern. So, Ag+ is originally [Kr] 5s24d9, but you remove one from 5s2 to make the 4d orbital full, so it becomes 5s1 4d10 and then a positive charge means removing one electron and it's easier to just remove the one from the 5s orbital so it becomes [Kr] 4d10.
