Question

electronegativity decrease down the group why

Answer 1

Hey there !

as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. Electronegativity increases as you move from left to right across a period on the periodic table.

Hope it helps you !

Answer 2

Answer:

Electronegativity of alkaline earth metals decrease down the group. In a group as atomic number increases, atomic radius increases. Nuclear attraction decreases. The tendency to attract shared pair of electron decreases down the group and hence electronegativity decreases
