The electronegativity of elements on the periodic table tends to increase_______.

Question

Quizplus · Accepted Answer

Electronegativity tends to increase as you move across a period from left to right because the number of protons in the nucleus increases, drawing the electrons closer and making them more attracted to the nucleus. Electronegativity also tends to increase as you move up a group (column), because the smaller size of the atoms in higher rows means the valence electrons are closer to the nucleus and more strongly attracted.
