Answer:

AS CALCIUM IS A METAL IT CAN DONATE ELECTRONS TO ATTAIN STABLE ELECTRONIC CONFIGURATION !

NEAREST STABLE CONFIGURATION IS OF ARGON !

TO ATTAIN ARGON'S CONFIGURATION CALCIUM SHOULD LOOSE 2 ELECTRONS.

SO, VALENCY OF CALCIUM IS -2

Answer:

The valency of calcium is 2.

Explanation:

Calcium is an alkaline earth metal.

The atomic number of calcium = 20

The electronic configuration of Ca = 1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6}4s^{2}

The valence shell contains two electrons. Either add 6 electrons (very tough) or lose 2 electrons for a stable octet configuration ( easy).

So the oxidation state of calcium is +2.

That is, the valency of calcium is two.
