Q7. Elements having +5 oxidation state is
Answer : Option D
Explaination / Solution:

The maximum oxidation state shown by a p-block element is equal to the total number of valence electrons (i.e., the sum of the s and p-electrons).

P:[Ne]3s23p3. Total valence electrons =5 so it will show +5 oxidation state. The stability of +5 oxidation state decreases down the group due to inert pair effect.
