Question

what is valency? give me some examples too

Pls explain it clearly​

Answer 1

Answer:

Valency: Valency is defined as the number of hydrogen atoms which combine directly or indirectly with one atom of an element. Example: One atom of nitrogen combines with three atoms of hydrogen to form ammonia gas. So, the valency of nitrogen is 3.For example, oxygen has six valence electrons, but its valency is 2. Some elements may have more than one combining power (or valency), while others have just one. For example, H →1; Mg→2; Al→3; C→4; N→3, and 5; P→3 and 5; O→2; S→ 2, 4 and 6; Cl→ 1; and Ne→0.
