Metals | Non−metals |
Metals react with oxygen to form basic oxides. 4Na+O2→2Na2O | Non-metals react with oxygen to form neutral or acidic oxide. C+O2→CO2 |
Metals react with water to form hydroxide and hydrogen. 2Na+2H2O→2NaOH+H2 | Generally, non-metals do not react with water. |
Metals react with dilute acids to form salt and H2. | Non-metals do not react with dilute acids and they cannot displace hydrogen. |
