Question

How does the metallic character vary in group 15?

Discuss the following property and its variation in the group 15 element:

Metallic character

Answer 1

1. Metallic character in group 15 elements is less than in group 14 due to smaller atomic size and higher ionization energy.
2. It increases down the group because atomic size increases and ionization energy decreases.
3. Valence electrons are held less tightly moving from N to Bi.
4. N and P are nonmetals; As and Sb are metalloids; Bi is metallic. This variation is due to changes in atomic size and nuclear charge down the group.
