Question

what is meant by ionisation energy

Answer 1

The ionization energy (IE) is qualitatively defined as the amount ofenergy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.

Answer 2

Hello friend _/\_

Your Answer ->>

Ionisation energy :-

→The term ionisation energy (IE) is defined as the energy that is required to remove the outer electron of an atom or molecule.

→The tendency to lose the outer electron is directly correlated to the ionisation energy – the lower the ionisation energy, the easier the removal ofthe electron.

→Within the group ofalkali metals, the ionisation energy for the removal ofthe outer electron decreases as a result ofthe increasing distance ofthis electron from the nucleus.
