Answer 2

Valency of C: 4 :: valency of N : 3

Step-by-step explanation:

• Valency is the measure of combining capacity of atoms or molecules.

• Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell.

• The number of bonds that an atom forms in order to make a compound is expressed by the valency of the element.

• Valence electron is the number of electrons in the outermost shell of an atom.

• Carbon has 4 electrons in outermost shell and requires 4 more to complete its octet. So, its valency is 4 which means it will make 4 bonds when reacting with other elements.

• Nitrogen has 5 electrons in outermost shell and requires 3 more to complete its octet. So, its valency is 3 which means it will make 3 bonds when reacting with other elements.
