Difference between metals and nonmetals
1. Metals have one to three electrons in their outer shell, whereas non-metals have four to eight electrons.
2. Metals are malleable, which means they can be beaten to thin sheets. On the other hand, non-metals are very brittle.
3. Metals have a high to moderate density, whereas non-metals have low to moderate density.
4. Metals are opaque and non-metals are transparent.
5. Metals are present in solid form at room temperature, and non-metals are present in solid and liquid forms at room temperature.
6. Unlike non-metals, metals are ductile, which means they can be stretched into wires.
7. Metals have a metallic luster, while non-metals do not.
8. Metals tend to lose their valence electrons, but non-metals share or gain valence electrons.
9. Metals are good conductors of electricity and heat, but non-metals are poor conductors.
