What type of ionization energy and electron affinity doe noble gases have?

Even though the periodic trends indicate that elements closest to the noble gases have higher ionization energy and electron affinity, the noble gases themselves are exceptions to this trend. They have full octets, therefore they are stable, which means they are less reactive and do not need to have very high ionization energy nor electron affinity to keep their electrons.

If we were to try to add or subtract an electron from a noble gas, it would require an extensive amount of energy.

Ionization energy is the energy required to remove an electron from an atom in the gaseous state. Because noble gases have a full octet, their ionization energies are actually quite high. Electron affinity is the amount of energy released when an electron is added to a neutral atom. Because noble gases have stable electron configurations, they have very low electron affinities.
