predicting the type of orbital

Postby halle young 4A » Tue Oct 22, 2019 10:19 pm

homework problem 1E.17

For each of the following ground-state atoms, predict the type of orbital (1s, 2p, 3d, 4f, etc.) from which an electron will removed to form the +1 ion: (a) Ge; (b) Mn; (c) Al; (d) Cu.

Can someone please explain part b? I am confused on how the answer is the 4s orbital.
thanks

The 4s sub-shell has a higher energy than the 3d sub-shell. The first electron removed is from the sub-shell with the highest energy (furthest from nucleus).

You remove an electron from the highest energy level (furthest from the nucleus). You can figure out the relative energy levels of orbitals using a periodic table and moving across each row from left to right.
