ELECTRONEGATIVITY

• Electronegativity is the ability of an atom to attract electrons in a covalent bond.
• Non-metals are more Electronegative.
• Most electronegative elements in the periodic table are :- Fluorine > Oxygen > Nitrogen ≥ Chlorine
• 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.
