Question

Which statement describes the general trends in electronegativity and metallic properties as the elements in period 2 are considered in increasing atomic number?

(1) Both electronegativity and metallic properties decrease.
(2) Both electronegativity and metallic properties increase.
(3) Electronegativity decreases and metallic properties increase.
(4) Electronegativity increases and metallic properties decrease.

Answer 1

The correct answer is 4.

This is because, as you move farther across a periodic group (left to right), because gaining electrons becomes easier, thus increasing electronegativity and decreasing metallic properties.
