Answer: The electron structure of [tex]Be^{2+}[/tex] ion is [tex]1s^2[/tex]
Explanation: Beryllium is the 4th element of the periodic table.
The electronic configuration of Be-element in its ground state is:
[tex]Be(Z=4):1s^22s^2[/tex]
For the Beryllium element to have +2 charge, two electrons must be removed from the electronic configuration. So, the electronic configuration for the [tex]Be^{2+}[/tex] ion is:
[tex]Be^{2+}:1s^2[/tex]
