1s1
1s2
2s1
2s2

The electron structure of ion is

Explanation: Beryllium is the 4th element of the periodic table.

The electronic configuration of Be-element in its ground state is:

For the Beryllium element to have +2 charge, two electrons must be removed from the electronic configuration. So, the electronic configuration for the ion is:
