Question

Ionisation energy and electron affinity of inert gases are very high-explain

Answer 1

Inert gases, also known as "noble gases," are the group 18 chemical elements on the periodic table. They are highly unreactive because its outermost atomic orbital has been filled to its maximum capacity of 8 electrons. ... Ionization energy is the energy required to remove a valence electron from an atom.

Answer 2

Ionization energy of noble gases is very high in comparison to other elements of the same period. This is due to extra stability on attaining the compete octet in out a shell.
