Question

As you move down a period of the periodic table from top to bottom, what happens to the elements' electronegativity?

A.
It decreases.

B.
It changes in relation to the number of electrons.

C.
It changes in relation to the number of protons.

D.
It increases.

Answer 1

A.) It decreases

Step-by-step explanation:

Generally, as you go from the top to the bottom of the periodic table (down a column), the electronegativity values of the elements decrease.

Also, as you move to the right of the periodic table (across a period), the electronegative values increase. The most electronegative elements are located on the top-right of the periodic table.
