Differentiate between metal and non-metal on the basis of their chemical properties

Solution:
Metals
1) Metals are electro-positive elements.
2) Metals combine with oxygen to form basic oxides.
3) Metal oxides and hydroxides are ionic in nature.
4) Reactive metals react with water to form metal hydroxide and hydrogen gas
5) Metals are reducing agents since they have a tendency to lose electrons

Non-metals
1) Non-metals are electronegative elements.
2) Non-metals combine with oxygen to form either neutral or acidic oxide
3) Non-metal oxides and hydroxides have covalent molecules.
4) Non-metals (except P4 or halogens) do not react with water.
5) Non-metals are oxidizing agents since they have a tendency to gain electrons
