Which element has the highest electronegativity? question options: a. si b. p c. s d.cl

D. Chlorine ha s the highest electronegativity.

Explanation:

The given elements are silicon, phosphorus, sulphur and chlorine.

Silicon lies in group four of the periodic table.

Phosphorus lies in group five of the periodic table.

Sulphur lies in group six of the periodic table.

Chlorine lies in group seven of the periodic table. They are on all the same period (third period)

Electronegativity of an element is the ability of an atom in a molecule of that element to attract electrons .

Electro negativity increases across a period (from left to right) and decreases down the group. This means that chlorine will be the most electronegative element among them
