Question

Varition on electronegativity

Answer 1

$\huge\mathtt\color{red} Answer$

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.

Electronegativity is dependent upon the size of the atom, since the attraction for electrons falls rapidly as the distance from the nucleus increases. ... However, when we move across a period in the periodic table, electronegativity increases, since the atomic size decreases across a period.
