Ionization Energy

Postby Albert Chen 1G » Sun Oct 24, 2021 4:13 pm

Ionization energy is defined as the energy needed to remove e- from an atom in its gas phase. Is there any reason why it uses the gas phase to calculate ionization energy?

Hi,
I think that the reason ionization energy is only considered when the atom is in gaseous state, is due to gaseous particle being further apart from each other thus there is minimal attraction between different particles. And because this attraction between different particles effect the ionization energy, we only consider the gas phase where it is very minimal compared to liquids or solids.
