Three differences between metals and non-metals on the basis of chemical properties :
| S. No. | Basis | Metals | Non-metals |
| 1 | Reaction with oxygen | Almost all metals react with oxygen to form metal oxide.
4Na + O2 → 2Na2O |
Non-metals react with oxygen to form acidic oxides.
C + O2 → CO2 |
| 2 | Reaction with water | Only reactive metals react with water to form oxides or hydroxides and liberate hydrogen gas.
2K(s) + 2H2O(l) → 2KOH(aq) + H2(g) |
Non-metals do not displace hydrogen from water too. |
| 3 | Reaction with diluted acid | All metals react with diluted acids to produce salt and hydrogen gas.
Zn + 2HCl(dil) →ZnCl2 + H2 |
Non-metals do not react with dilute acids |
