18.3 Structure and General Properties of the Metalloids
A metalloid is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals. There is no standard definition of a metalloid and no complete agreement on which elements are metalloids. Despite the lack of specificity, the term remains in use in the literature of chemistry. The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony and tellu… Weba. They form compounds with very bright colors. b. They exist as single atoms rather than as molecules. c. They are highly reactive with both metals and nonmetals. d. They are extremely rare in nature. ____ 31.
