Question

What is meant by Ionization potential?

Answer 1

The minimum amount of energy required to remove an electron from the outermost orbit of an isolated gaseous atom is known as it's ionisation potential.

Answer 2

Answer:

The ionization energy or ionization potential is the energy necessary to remove an electron from the neutral atom. It is a minimum for the alkali metals which have a single electron outside a closed shell. It generally increases across a row on the periodic maximum for the noble gases which have closed shells.
