Nonmetals are electronegative...

And metals are electro positive..

Answer 2

Answer with explanation:

A property of an atom to attract electrons for bonding themselves is known as Electro-negativity.

In Modern Periodic table , the electro-negativity increases from left to right and decreases when you go down to a group.

The Pauling scale of electronegativity is the most general scale of elecrto negativity that depends on bond dissociation energies.

It sets relative values for the elements in Periodic Table .

For example : Most reactive element "Fluorine" is assigned to value of 4.0.
