List in tabular from three chemical properties on the basis of which we can differentiate between a metal and a non-metal.
Solution
| Metals | Non-Metals | |
| 1. | Metals react with oxygen to produce basic oxides. | Non-metals react with oxygen to produce acidic or neutral oxides. |
| 2. | Metals react with water to produce metal hydroxide and hydrogen gas. | Non-metals do not react with water to produce hydrogen gas. |
| 3. | Generally, metals do not combine with hydrogen except sodium, potassium, calcium, and magnesium which form ionic hydrides on reacting with hydrogen | Non-metals react with hydrogen to form covalent hydrides. |
