Why do noble gases have positive electron gain enthalpy?

Hey !


Noble gases already have a very stable fully filled electronic configuration. Addition of another electron to a neutral inert gas atom would lead to high electronic repulsion and it would also destroy the already stable electronic configuration,which is highly unfavorable.

So, addition of an electron to the neutral atom requires a large amount of energy. As a result, the EGE of noble gases is positive




hope it helps

Energy is released when an electron is added to the atom. ... Noble gases have large positive electron gain enthalpy. This is because the extra electron is placed in the next higher principal quantum energy levels. Thus, a highly unstable electronic configuration is produced.
