Question

Ionization enthalpy of oxygen is equal to which novel gas

Answer 1

Hey user..

Ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous atoms.

Atoms are more stable when they have full valence shells. It's almost like all the atoms are on a quest to have a full shell. Noble gases already have that last level full of electrons so they hold on to them as strongly as possible.

But you are talking about oxygen and nobel gases, so actually they are not even comparable,noble gases have highest IE in there respective groups even more than halogens
