IT MEANS ABOUT THE POSITIVE AND NEGATIVE ENERGY EMITTED BY MAGNET . THE POSITIVE IS ELECTROPOSITIVITY AND ELECTRONEGITIVITY IS NEGATIVE ONE. WHEN ELCTRICITY IS PASSED.

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.
ELECTROPOSITIVITY
- Electropositivity is the ability of an atom to withdraw a shared pair of electrons in its combined state.
- Metals are more Electropositive.
- It increases down the group.
- It decreases along the period.
- Example :- Sodium(Na) is a electropositive element & able react with zinc oxide to reduce it metallic zinc, while itself being oxidized to the oxide.
