Question

define electronegativity ? how it will vary in groups and periods​

Answer 1

Electronegativity is the tendency of the element to attract the shared pair of electrons towards itself.The higher the electronegativity of an atom, the greater its ability to attract shared electrons. The electronegativity of atoms increases as you move from left toright across a period in the periodic table. The electronegativity of atoms decreases as you move from top to bottom down agroup in the periodic table.

Answer 2

Explanation:

The higher the electronegativity of an atom, the greater its ability to attract shared electrons. The electronegativity of atoms increases as you move from left to right across a period in the periodic table. The electronegativity of atoms decreases as you move from top to bottom down a group in the periodic table.

I Hope it worked this is the correct answer
