Answer 1

Answer:

answer is 3

valency of nitrogen is -3

Answer 2

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

Explanation:

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

• it is the capacity of an atom of a single element to react and combine with particular numbers of atoms of another element.

• Valency is the combining power of an element. 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.
• Carbon has a total of 6 electrons and 4 electrons in outer most shell. It requires 4 more electrons to complete its octet i.e. 8 electrons in outermost shell. So, its valency is 4.
• Nitrogen has a total of 5 electrons and 3 electrons in its outermost shell. It loses 3 electrons to complete octet that is 2 electrons in its k-shell. So, its valency is 3.
