3. METALS & NON METALS
Metals:
Any of various opaque ductile & typically lustrous
substances that are good conductors of heat and
electricity and yield basic oxides and hydroxides.
NonMetals:
The element which form negative ions have
acidic oxides and are generally poor conductors of
heat and electricity.

5. METALS
Good electrical conductors and heat conductors
Malleable(Can be beaten into thin sheets)
Ductile ( Can be stretched into a wire)
Possess metallic Lester
Opaque as thin sheet
Solid at room temperature (except Hg)
6. NON METALS
Poor conductors of heat and electricity
Brittle – if a solid
Non-ductile
Do not posses metallic luster
Transparent as a thin sheet
Solid liquid or gas at room temperature
