You got scandium...Z=21, i.e. 18 electrons to distribute in the trication.

Explanation:

And so we follow the usual "Aufbau scheme"...

underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^1)_"electronic configuration of scandium metal"

underbrace(1s^(2)2s^(2)2p^(6)3s^(2)3p^(6))_"electronic configuration of scandium trication"
