The correct order of ionic radius of nitrogen family is
Options
- AN ³⁻ P ³⁻ As ³⁻ Sb ³⁻ Bi ³⁻
- BN ³⁻ P ³⁻ Sb ³⁻
- CP ³⁻= As ³⁻ Bi ³⁻
- DN ³⁻ Bi ³⁻ Sb ³⁻
Correct answer
A. N ³⁻ P ³⁻ As ³⁻ Sb ³⁻ Bi ³⁻
Step-by-step solution
Atomic raddii as well as ionic radii increases down the group. All the element of the nitrogen family contain same charge, i.e. - 3. Thus, the correct order of ionic radius of nitrogen family is N ³⁻ P ³⁻ As ³⁻ Sb ³⁻ Bi ³⁻
