We are given:

Calcium is the 20th element of the periodic table having electronic configuration $1s^22s^22p^63s^23p^64s^2$

It has 2 valence electrons.

The element present in period 3 and have the same number of valence electron or in the same group is magnesium.

Hence, the element having similar chemical properties that of calcium present in period 3 is magnesium.
