Question

differentiate between electropositive and electronegative compounds

Answer 1

In each ionic compound the element have +charge &- charge. Only bcoz of it they attract each other. The compound which (element) give its electron and become electropositive. The element receive electron are electronegative.

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.
• Caesium is most electropositive metal.
• 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.
