The chemical symbol – “Ca” indicates calcium element.

Atomic number of Calcium = 20

Electronic configuration – 1s2 2s2 2p6 3s2 3p6 4s2.

+2 charge of an element indicates two electrons remove from their electronic configuration.

Ca2+ electronic configuration - 1s2 2s2 2p6 3s2 3p6

From the above configuration, the outer shell of has fully filled electrons. Therefore, Ca2+ has completely filled electronic configuration.
