Karo-lina-s [1.5K]

Elements 3 to 10 (Li to Ne) show a more or less steady increase in ionization energy.

<h3>What is ionisation energy?</h3>

The amount of energy required to remove an electron from an isolated atom or molecule.

The major difference is the increasing number of protons in the nucleus as you go from lithium to neon. That causes greater attraction between the nucleus and the electrons and so increases the ionization energies. In fact the increasing nuclear charge also drags the outer electrons in closer to the nucleus.
