what would the electron configuration for Cr3+ be?

I can't figure out what it would be. I've tried [Ar]4s^1but that doesn't seem to be right. I'm not sure what to do then b/c only having one e- in the d sublevel would not leave the cation with a stable configuration, and if 2 of the three came from the 4s, then one from the 3d, it would still not be very stable.I know this is supposedly one of the coinage metals, so it'll be different but I can't figure it out.Thank you all for your help!

The electronic configuration of Cr(24) atom is 1s2 2s2 2p6 3s2 3p6 4s1 3d5( completely half-filled d-orbital ) and that of Cr3+ is [Ar] 3d3.... Show More
