Metalloids • Have some characteristics of metals, some of nonmetals. • For instance, silicon looks shiny, but is brittle and fairly poor conductor. 2 Alkali Metals (1A) Their reactions with water are famously exothermic. Produce bright colors when ...
An elementary substance, as sodium, calcium, or copper, whose oxide or hydroxide has basic rather than acid properties, as contrasted with the nonmetals, or metalloids. No sharp line can be drawn between the metals and nonmetals, and certain elements partake of both acid and basic qualities,...
What About Metalloids? In addition to metals and nonmetals, there are also metalloids on the periodic table. Metalloids are unique because their properties fall somewhere between those of metal and nonmetal elements. They aren’t particularly lustrous, nor are they are particularly dull. Rather, th...
Metalloids Invertebrate decline International guidelines Environmental pollution 1. Introduction Terrestrial invertebrate bioabundance and biodiversity are declining (Wagner, 2020). Since invertebrates are basal to terrestrial food webs and provide key ecosystem services, the short-term ecological consequences of...
^The term metalloid originally referred to nonmetals. Its more recent meaning, as a category of elements with intermediate or hybrid properties, became widespread in 1940–1960. Metalloids are sometimes called semimetals, a practice that has been discouraged, as the term semimetal has a different ...

Nonmetals, however, are mostly poor conductors of heat and electricity. They are not ductile and malleable, and many of them are gases at room temperature. Then come the metalloids, which are neither metals nor nonmetals; they possess some properties or metals while others of nonmetals. ...
