metals- react with oxygen to give basic oxides
react with water to give metal oxide or hydroxide and hydrogen gas.
metal react with dilute acids to give salt and water
metal react with salt solutions of another metal to form their own salt solution if they are reactive enough.
metals react with chlorine to give ionic chlorides.
metals react with hydrogen to give metal hydrides.
non metals- react with oxygen to give acidic or neutral oxide.
do not react with water
do not react with dilut acids
a non metal displaces less reactive non metal from its salt solution
non metal react with chlorine to give covalent chlorides
non metals react with hydrogen to give covalent hydrides.
Metals
Non-Metals
1. Oxides of metal are basic in nature.
1. Oxides of non-metals are acidic in nature.
2. Metals displace hydrogen from dilute acids.
2. They cannot do so.
3. Metals form chlorides which are electrovalent or ionic compounds.
3. Non-metals form chlorides which are covalent compounds.
4. they displace hydrogen from water

Metals refers to the natural elements that are hard, shiny, opaque and dense. Non-metals implies those chemical substances that are soft, non-shiny, transparent and brittle. Most metals are hard, except sodium. Most non-metals are soft, except diamond
