(1) atomic radius
(2) IE
(3) EN
(4) electron gain enthalpy or electron on affinity

Answer 1

Answer:

a) Atomic Radius

Explanation:

This is called periodic property.

This is called periodic property.a) Atomic radius: The distance between the nucleus and outermost orbitals called as atomic radius. Group : Atomic radii increases from top to bottom in a group, the atomic number of the element increases. Period : Atomic radii of elements decrease across period from left to right.
