ELECTRONEGATIVITY

• Electronegativity is the ability of an atom to attract electrons in a covalent bond.
• It increases from moving left to right in a period due to increase in effective nuclear charge.
• It decreases as we move from top to bottom as size of atom increases.

ELECTROPOSITIVITY

• Electropositivity is the ability of an atom to withdraw a shared pair of electrons in its combined state.
• It increases down the group.
• It decreases along the period.
