Mention the difference in chemical characteristics of the two hydrides obtained when hydrogen combines with two elements having atomic number 17 and 20.

Text Solution

Verified by Experts

The highly electronegative CL atom having atomic number 17 combines with hydrogen to from the covalent hydride H-CL. on the other hand, the highly electropositive Ca atom having atomic number 20 combines with hydrogen to from the ionic hydride Ca`H_(2)`.
