Answer 1

The combining power or capacity of an element is known as its​ valency.

Explanation:

• The number of electrons present in the outermost shell of an electron determine the combining power or capacity of an element.
• The elements react with another element so that the electrons in the outermost shell can be completed.
• The valence electrons are the ones which take part in a chemical reaction and determine how reactive a particular element is.
