| 1. | Have a strong tendency to lose electrons to from cations. | 1. | Non-metals are strong tendecy to accept electrons to from anions. |
| 2. | Metals are strong reducing agents. | 2. | Non-matels are strong oxidising agent. |
| 3. | Metal have low ionization enthalpies. | 3. | Non-metals have high ionization enthalpies. |
| 4. | Metals form basic oxides and ionic compounds. | 4. | Non-metals from acidic oxides and covalents compounds. |
