Question

Name the following periodic property.

Amount of energy required to remove an electron from an isolated gaseous atom.

Answer 1

Ionization enthalpy:-

1. Ionization enthalpy or ionization energy is the amount of energy required for the removal of an electron from an isolated gaseous atom.
2. Ionization enthalpy increases across a period from left to right and decreases as we go down the group.

Hence, the amount of energy required to remove an electron from an isolated gaseous atom is known as ionization enthalpy.
