A metal is a chemical element that is a good conductor of both electricity and heat and forms cation and ionic bonds with non-metal.
Two properties of metals and non-metals:
Metals - They are malleable
-They are lustrous
Non-metals - they are poor conductor of heat and electricity compared to metals.
- they have high electronegativity
Three physical properties of metals:
1)Metals are solid at normal temperature except mercury
2)Metal transform to liquid from solid and to gas from liquid at definite temperatures which are high for most metals except mercury, sodium and potassium.
3)Metal reflects equally nearly all visible electromagnetic waves.
