Answer :
Metals
- A metal is a material (an element, compound, or alloy) that is typically hard, opaque, shiny, and has good electrical and thermal conductivity.
- Examples :- Iron, copper, aluminium ,magnesium ,sodium, lead etc.
- Metals , in their pure state have a shinning surface This property is called Metallic lusture .
Non metals
- A non-metal is an element that when forming an ionic compound with a metal, accepts electrons to attain a full outermost shell. This is because it is easier for a nonmetal to reach noble gas electronic configuration than a metal.
- Examples :- Carbon , Sulphur , Iodine , Oxygen , Hydrogen etc.
- The non metals are either solids or gases except bromine which is a liquid
