1.	Compare metals and non-metals.
Answer» 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.
