Which statements describe properties that are unique to metalloids? Check all that apply. Metalloids are shiny. Metalloids are semiconductive. Metalloids are solid. Metalloids are amphoteric. Metalloids are brittle.

The properties of metalloids are listed below. However, the degree of uniqueness of these properties is uncertain, seeing as metalloids have properties that are between metals and non-metals.

Explanation:

Metalloids are also known as semi-metals. Examples include Silicon, Arsenic,Carbon,etc.

Metalloids are semi-conductive: they are not as good conductors of heat and electricity as metals are.Metalloids exists mostly as solid under normal conditionsThey possess amphoteric properties ,i.e.they can act as either acids or bases,e.g arsenic salts.They are brittle, generally possessing low elasticity.Metalloids have metallic lustre i.e. they are shiny; but can also be dull depending on which allotrope is being exhibited.
