In general, how do the physical properties of non metals relate to the properties of metals ?

Question

They are different from the properties of metals
They are more noticeable than the properties of metals

Answer 1

In general, the physical properties of nonmetals and metals are quite different, and this difference is evident in several key areas:

1. Electrical Conductivity: Metals are typically good conductors of electricity due to the presence of free-moving electrons. In contrast, nonmetals are generally poor conductors, with many being insulators.

2. Physical State: Most metals are solid at room temperature (except for mercury), while nonmetals can be gases (like oxygen and nitrogen), solids (like sulfur and phosphorus), or liquids (like bromine).

3. Luster: Metals usually have a shiny appearance (metallic luster), whereas nonmetals tend to have a dull appearance.

4. Malleability and Ductility: Metals are malleable (can be hammered into thin sheets) and ductile (can be drawn into wires). Nonmetals are generally brittle in solid form and cannot be shaped in the same way.

5. Density and Melting Points: Metals usually have higher densities and melting points compared to nonmetals, which can vary widely.

6. Reactivity: The chemical reactivity can differ significantly; metals tend to lose electrons during chemical reactions, while nonmetals often gain or share electrons.

Overall, the differences in physical properties between nonmetals and metals are indeed quite pronounced, making it clear that they are not only different from each other but also that these differences are significant in various applications.
