What are the major differences between metals and non-metals?

Text Solution

Verified by Experts

Metals have a strong tendency to lose electrons to form cations they are strong reducing agents, have low ionisation enthalpies, have less negative electron gain enthalpies, low electronegativity and form basic oxides ad ionic compounds. Non-metals have a strong tendency to accept electrons to form anions. they are strong oxidising agents, have high ionisation enthalpi9es, have high negative electron-gain enthalpies, high electronegativity and forms acidic oxides and covalent compounds.
