sum of digits of the group number of p block which do not follow the trend of atomic raduis i.e. do not consider radioactive elements​

Answer 1

All Group 15 elements tend to follow the general periodic trends:

Electronegativity (the atom's ability of attracting electrons) decreases down the group.

Ionization energy (the amount of energy required to remove an electron from the atom in its gas phase) decreases down the group.

Atomic radii increase in size down the group.
