So, I remember a while ago my teacher was talking about how chromium has an unusual electron configuration that basically sticks out like a sore thumb in terms of following the filling principles of orbital subshells that we were taught.

Try as I did, possessing the pea brain that I do I did not really get why chromium is such a special snowflake in it's electron configuration and why its orbitals are different from the rest of the 3d elements. The answer seems to be that half filled and fully filled subshells are particularly stable, ok, fine. THE PROBLEM though is that when ions form this makes no sense at all to me.

Someone smart, halp? What's the deal with chromium's shell filling? I'm speaking in terms of ion formation because that's where it started to make no sense at all to me. In a compound a chromium atom has a ground state config of [Ar] 3d6, but why is this so?

WHAT IS HAPPENING

Also to make this thread less boring and gay for people who find this stuff unbearable, here are some cool pictures of chromium solutions:
