Question
Differentiate between metals and non-metals on the basis of their chemical properties.

Solution
| Sr. No. | Metals | Non-metals |
| 1. | Metals form basic oxides. | Non-metals form acidic oxides or neutral oxides. |
| 2. | Metals displace hydrogen from water (or steam). | Non-metals do not react with water (or steam) and hence do not displace hydrogen from water (or steam). |
| 3. | Metals displace hydrogen from dilute acids. | Non-metals do not react with dilute acids and hence do not displace hydrogen from dilute acids. |
| 4. | Metals form ionic chlorides with chlorine. These ionic chlorides are electrolytes but non-volatile. | Non-metals form covalent chlorides with chlorine (which are non-electrolytes but volatile). |
| 5. | Metals usually do not combine with hydrogen. Only a few reactive metals combine with hydrogen to form ionic metal hydrides. | Non-metals react with hydrogen to form stable, covalent hydrides. |
