Question

The amount of energy released when one or more electron is added to the neutral atom

▪︎electron affinity
▪︎electronegativity​

Answer 1

Electron affinity

Step-by-step explanation:

Basically, electronegativity is the tendency of an atom to attract the electrons in a chemical bond towards itself but electron affinity is the energy change that occurs when an electron is accepted by an atom in its gaseous state to form an anion.

Hope it helps :)

Answer 2

ELECTRON AFFINITY

Step-by-step explanation:

Electron affinity is a measure of the energy released when an extra electron is added to an atom. Electron affinities are measured in the gaseous state.
