Sn3+?
« on: February 24, 2013, 10:07:29 PM »
Can anyone tell me why there is no Tin(III), but there is Tin(IV) and Tin(II)? I can't seem to find it online... Thanks!

Tin(II) would have the electron configuration [Kr]5s24d10
Tin(IV) would have the electron configuration [Kr]4d10

Tin(III) would have an electron remaining in the 5s orbital which would be unstable, but losing 2 or 4 electrons allows all of its orbitals to be full which makes it more stable
