Question

what are metalloids ? How are they different from metals​

Answer 1

Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal.

Answer. Metalloids have properties in between those of the metals and non-metals and are semiconductors (whereas metals are conductors and nonmetals are not conductors) and used extensively in circuitry (like computer chips). ... They can be shiny (have luster) or not whereas all metal are shiny

Answer 2

Explanation:

metalloids have properties in between those of the metals and non-metals and are semiconductors (whereas metals are conductors and nonmetals are not conductors) and used extensively in circuitry (like computer chips).

They are all solids at room temperature, not quite as malleable as metals....but not quite as brittle as nonmetals. They can be shiny (have luster) or not whereas all metal are shiny.
