**DrBob222**, Thursday, September 29, 2011 at 4:32pmAs is [Ar]3d10 4s2 4p3. To make the +3 ion we remove the last three electrons so the last electron added is the 4s.

n = 4

all s electrons are l = 0

the spin of an s electron is either +1/2 or -1/2. You should be able to pick out the answer from this.
