Which pattern in electronegativity do elements in the periodic table display?

Question

(1 point)
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.
• 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.

Answer 1

The correct statement 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 the increasing positive charge of the nucleus, which attracts the bonding electrons more strongly. Additionally, electronegativity decreases as you move down a group because the increasing distance between the nucleus and the valence electrons makes it harder for the nucleus to attract bonding electrons.
