Question

Electron affinity decides electronegativity and electropositivity.

• A. True
• B. False

Answer 1

The correct option is A True

The electron affinity of an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion. Atomic size decides the ionisation energy and electron affinity. Electron affinity becomes less negative down a group. Electron affinity decides electronegativity and electropositivity.
