Electronic Configuration of calcium ion: Ca²⁺
1s², 2s², 2p⁶, 3s², 3p⁶
Explanation:
Calcium belong to group IIA and known as alkaline earth metals.
it have two electrons in outer most orbital.these outer two electrons are involve in bondingcalcium lose these two electron and form cationcation have 2+ chargecalcium have total twenty electronsElectronic Configuration of calcium atom: ²⁰Ca
1s², 2s², 2p⁶, 3s², 3p⁶, 4s²
When calcium ion is form it loses two electron and have 2+ charge on it.
and have total of 18 electrons
So,
Electronic Configuration of calcium ion: Ca²⁺
the last filled orbital will be 3p⁶
1s², 2s², 2p⁶, 3s², 3p⁶
