Which one of the following describes the correct trends in electronegativity in the periodic table?
A) increases across a period and decreases down a group
B) decreases across a period and decreases down a group

D) decreases across a period and increases down a group

Question

Quizplus · Accepted Answer

Electronegativity increases across a period due to the increasing nuclear charge, which attracts the bonding pair of electrons more strongly. It decreases down a group as the atomic radius increases, making the attraction between the nucleus and the bonding pair of electrons weaker.
