Factors Affecting:
(a) Electron Affinity:
- Atomic size: Smaller atoms have higher electron affinity due to stronger nuclear attraction on electrons.
- Nuclear charge: Higher nuclear charge increases electron affinity as the atom more readily accepts electrons.
(b) Electronegativity:
- Atomic size: Smaller atoms have higher electronegativity as they pull shared electrons more strongly.
- Nuclear charge: Higher nuclear charge increases electronegativity due to a stronger attraction on the shared electrons.
