Electronegativity is the tendency of an element to attract the shared pair of electrons towards itself in a covalently bonded molecule. Electronegativity of an element is inversely proportional to its atomic size. It means with increase in atomic size , electronegativity of an element decreases.
1. We know that atomic size increases down the group. Therefore electronegativity decreases down the group.
2. The attraction between the outer electrons and the nucleus increases, as the atomic radius decreases in a period. The electronegativity also increases.
