Question

What is ionization enthalpy and electron affinity

Answer 1

Answer:

energy requires to remove an electron from outer shell is called ionization enthalpy energy liberated when an electron added to an atom is electron affini

Answer 2

Answer:

Ionisation Enthalpy is the energy that is required to remove an electron from the outermost shell of an atom.

E.g. =>

Configuration of Na => [Ne] 3s1

Here , Ionisation Enthalpy is the energy required to remove the electron from the s subshell.

Electron Affinity is the energy released when an atom accepts an electron.

Configuration of Cl => [Ne] 3s2 3p5

Here , Electron Affinity is the energy released after the addition of the electron into the p subshell.
