Hello, I'm confused about "the higest quantum principal number" If an element loes electron and becomes a cation. The subshell with the "highest quantum princple number" empty first.
For example: Zn+2. In its neutral state it has 30 electrons, it loses 2 electrons, and the correct electronic configuration is 1s2, 2s2, 2p6, 3s2, 3p6, 4s0, 3d10. Can someone explain how do I determine the higest quantum principle number?
Thanks
