a) metals conduct electricity and heat while non metals do not(exception graphite), metals are lustrous, malleable and ductile while non metals are not
b)i)metals conduct electricity well because they allow the electrons to pass through them ,ii) this is so because molten iron is the best for joining two machine parts or for welding

ok?
if not please tell

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 tempera

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.
