Answer : Electron affinity (Eea) of an atom or molecule can be defined as the amount of energy released or past, when an electron to a neutral atom or molecule in the gaseous state to form a negative ion.Chlorine is considered the element that has the greatest electron affinity in the modern periodic table.The general formula is X + ----> + energyIt is found that the nonmetals have more positive Eea than metals.The electron affinity increases across the group, from left to right in the modern periodic table. Elements with a small core have a high electron affinity.
