Silver Electron Configuration

Postby Nina Fukui 2J » Mon Nov 23, 2020 11:05 pm

Hi everyone,
quick question:
Why is silver's electron configuration [Kr] 5s1, 4d10? By the usual order it would be [Kr] 5s2, 4d9

The d-orbital is more stable when it has either 5 electrons or 10 electrons (either half filled or filled entirely). Therefore, whenever the d-orbital seems like it should have 4 electrons or 9 electrons, an electron is taken from the s-orbital to make that number either 5 electrons or 10 electrons in order to make it more stable. Hope that helps!

Elements in the same group as Cu would also “act” like Cu. Copper is one of our exceptions in electron configurations: its d-orbital will have a full shell (3d10 4s1). Any element under Cu will act the same so silver’s d orbital will also have a full shell.

This is because the species is more stable if all of the orbitals in the d state are filled with 2 electron so an electron from the 5s state will move to the 4d state

Silver falls into the coinage metals group (Au, Ag, Cu) which always have a (n-1)d10 ns1 configuration

It's more stable if it's [Kr] 4d10 5s1. When it's [Kr]4d9 5s2, it's pretty unstable which causes one of the electron from 5s2 to jump to the 4d orbital.

The unstable nature of unfilled orbitals allow silver to "borrow" an electron from the s orbital to the d, to make it complete.

Know that the 5s orbital is of a higher energy level than the 4d level. If the lower levels aren't filled completely first, then the higher energy levels will not be able to carry electrons in a stable state, as they will want to fall to a tighter level.

Hi, I think silver's electron configuration is [Kr] 4d10 5s1 because it's more stable since the d-orbital is completely occupied. Hope this helps!

This is because silver is more stable this way, with the d-orbital fully occcupied
