Answer 1

Metals

• Metals are usually hard solids, lustrous, ductile, malleable, good conductors of heat and electricity, have high melting and boiling points,
• Examples of metals: Iron(Fe), Copper(Cu), Silver(Ag).

Nonmetals

• Non-metals usually have a dull surface, soft solids, brittle, low melting point and boiling points, bad conductors of heat and electricity, etc. properties.
• They are bad conductors of electricity.

• Carbon$\left(\mathrm{C}\right)$, sulfur$\left(\mathrm{S}\right)$, oxygen$\left({\mathrm{O}}_2\right)$, and hydrogen$\left({\mathrm{H}}_2\right)$ are some examples of nonmetals.
• Except for bromine$\left({\mathrm{Br}}_2\right)$, which is a liquid, the nonmetals are either gases or solid.
