Question

what is the difference between electronegativity and electron effinity?

Answer 1

Electronegativity is a chemical property that says how well an atom can attract electrons towards itself. The electronegativity of an atom is influenced by the atom's atomic number and the distance between the atom's valence electrons It was first theorised by Linus Pauling in 1932.

The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.

Answer 2

Electronegativity is the ability of an atom in a molecule to pull the electrons towards itself.

And electron affinity refers to the energy change in the neutral atom when it attracts and electron.
