Question

Which pattern in electronegativity do elements in the periodic table display? (1 point)

Electronegativity increases from left to right within a row of the periodic table.

Electronegativity is highest on the left and right sides of the periodic table, and lowest in the middle of a row.

Electronegativity is lowest on the left and right sides of the periodic table, and highest in the middle of a row.

Electronegativity decreases from left to right within a row of the periodic table.

Answer 1

The correct answer is: **Electronegativity increases from left to right within a row of the periodic table.**

In general, electronegativity tends to increase as you move from left to right across a period due to increasing nuclear charge, which attracts bonding electrons more strongly. It also tends to decrease as you move down a group because of the increasing distance between the nucleus and the valence electrons, as well as the shielding effect from inner electrons.
