Explanation:

Sodium and Calcium both are very reactive metals which have higher reduction capacity than other metals.

if I say it in a simple meaning sodium has valency 1+ and Calcium also has valency 2+

sodium has valency oneplus because it has 1 electrons in its outermost shell which it donates to acquire positive valency.

calcium has valency 2 + because it has 2 electrons in its outermost shell which is donated by it to acquire the positive valency of 2.

the chemical symbol for Sodium is Na for calcium is Ca
