p-Block Elements: Nitrogen Family VA-Group Elements |
VA- GROUP ELEMENTS
NITROGEN FAMILY [ VA-GROUP(ns2, np3)]
The elements of this group are called pniconides (means suffocation).
Electronic Configuration
The general electronic configuration of this group of elements is ns2 np3.
For example:
7N : 1s2, 2s2, 2p3
15P : 1s2, 2s2 2p6, 3s2 3p3
Atomic and Physiochemical Properties
• Atomic Radii: On moving down the group, the atomic radii increases. However, this increase is not much from As to Bi because of poor screening effect by inner d or f-orbital electrons.
• Ionization Enthalpy: On moving down the group, the values of ionization enthalpy ...
