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 lowest on the left and right sides of the periodic table, and highest in the middle of a row.
electronegativity is highest on the left and right sides of the periodic table, and lowest in the middle of a row.
electronegativity decreases from left to right within a row of the periodic table.

Explanation:

Electronegativity is the ability of an atom to attract electrons in a chemical bond. In a period (row) of the periodic table, as the atomic number increases from left - right, the number of protons in the nucleus increases, and the outer - shell electrons are closer to the nucleus. This leads to an increase in the attraction for electrons, so electronegativity increases from left to right within a row.

Answer:

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