State four differences between metals and non-metals

Explanation:

Metals:

• Metals are lustrous in nature i.e. have shiny appearance.
• Metals are good conductors of heat and electricity.
• Metals are malleable and ductile in nature.
• Metals have high melting and boiling points.

Non-Metals

• Non-metals are dull in appearance.
• These are poor conductors of heat and electricity except graphite.
• These are soft in nature and can exist in all three states of matter.
• Having low melting and boiling point.

Final answer: Metals are lustrous while non-metals are dull, metals are good conductor of heat and electricity while non-metals are bad, malleable and ductile nature shown by metals while non-metals are soft.
