Question

What is the ground state electron configuration for Zn ?

Answer 1

`1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^10`

Explanation:

The atom is electrically neutral. Therefore, the number of protons is equal to the number of electrons.

`"_30^65Zn`

The zinc atom has 30 protons `=>` 30 electrons.

`1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 4s^2, 3d^10`
