Question
What are the major differences between metals and non-metals?
✓
Answer
(i) Metals have property to loose electron and form cations while non-metals accepts electron and form anion.
(ii) Metals are more electropositive while non-metals are electronegative.
(iii) Metals are strong reductants while non-metals are oxidants.
(iv) Metals are generally solid while non-metals are either solid or gas.
(v) Metallic oxides are basic or amphoteric, while oxides of non-metals are acidic or neutral.
(vi) The melting and boiling points of metals are high while that of non-metals are low.
(vii) Metals are conductor of heat and electricity while non-metals are not.
(viii) Metals are ductile and malleable while non-metals are brittle.
