  Metals                                     Non-metals 
Metals are electro-positive. Non-metals are electronegative.
Metals reacts with oxygen to form basic oxides.
4Na+O2​→2Na2​O
Non-metals react with oxygen to form neutral or acidic oxide.

C+O2​→CO2​

Metal oxides and hydroxides bonds have ionic bonds. Non-metal oxides and hydroxides have covalent bonds.
Metals react with water to form hydroxide and hydrogen.

2Na+2H2​O→2NaOH+H2​

Non-metals do not react with water.
Metals react with dilute acids to form salt and H2​. Non-metals do not react with dilute acid and they can not displace hydrogen.
Metals react as reducing agent by donating electrons.

Na→Na++e−

Non-metals are oxidizing agents that can gain the electrons.

Cl2​+e−→Cl−
