The Correct Option is C
Solution and Explanation
Correct answer: 3
Explanation:
Elements in the VA group (Group 15) of the modern periodic table have 5 valence electrons in their outermost shell. To achieve a stable octet configuration, they typically gain 3 electrons.
Hence, their common valency is:
Valency = 8 - number of valence electrons = 8 - 5 = 3
So, the valency of Group VA elements like nitrogen, phosphorus, arsenic, etc., is usually 3.
