Question

electronegativity .give its trend in periodic table. ​

Answer 1

So, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. Electronegativity increases as you move from left to right across a period on the periodic table.

Answer 2

Electronegativity is the tendency to attract the shared pair if electron towards itself from an atom.

Since nuclear charge increases along the period so the electronegativity also increases proportionally.

Down the group nuclear charge decreases so the electronegativity will also decrease.
