Definition metal and non METALS
METALS: METALS possesses luster in their pure state. Metal are hard. It possesses property of marketability and ductility. Metal are good conductor of heat and electricity and their melting points are high. Metals are sonorous.
Metal combine with oxygen to form metal oxides.
Oxides of alkali metals are soluble in water.
NON METALS:
NON METALS are either solids and gas. they are neither malleable nor ductile.they are NON conductor of heat and electricity graphite it is conductor they are melting points and boiling point are the low.
Diamond it has the highest melting points .
