why inert gas have lowest E.A
Answers
Large atoms have low ionization energy and low electron affinity. Therefore, they tend to lose electrons and do not tend to gain electrons. ... Any electrons added to a noble gas would have to be the first electron in a new (larger) energy level. This causes the noble gases to have essentially zero electron affinity.
Why do inert gases have the highest ionization energy in the periodic table ?
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. Electrons in an atom's outermost atomic orbital are called, "valence electrons." Having 8 valence electrons is the most stable energy state (meaning lowest in energy) that an atom in its respective period can exist in. This explains why it is unlikely that inert gases will participate in chemical reactions because this will involve losing, gaining, or sharing a valence electron. If this were to happen, they will deviate from their lowest energy state of 8 valence electrons and move to a state of higher energy since they no longer have that full octet in their outermost atomic orbital.
