Question

Of the following elements, which has the highest electronegativity ? A) Sc B) P C) S D) As

Answer 1

Got a Periodic Table...?

Explanation:

As we face the Table, electronegativity INCREASES across the Period from left to right as we face the Table. It decreases down the Group. And this is a consequence of nuclear charge, and the shielding offered by FULL electronic shells. Anyway, you should look up a Table of electronegativities.
