METALS AND NON-METALS

METALS AND NON-METALS
Metals are those element which are mostly solid and hard. They reflect light from their surfaces and are good conductors of heat and electricity. Some metal are ductile, these can be pulled into wires. Some metals are malleable, these can be bent or hammered into desired shapes or sheet, iron, gold, silver, copper, and sodium, potassium and mercury are the example of metals.
Non-Metals are usually soft and bad conductors of heat and electricity. However graphite (a form of carbon) is a good conductors of electricity. Non-meals cannot be drawn into wires or sheet because they are brittle. Non-metals except bromine exist, both in solid and gaseous states. Bromine is the only liquid non-metal. Example: - carbon, Sulphur, chlorine, bromine, hydrogen, oxygen, nitrogen.
