What Is A Metalloid, On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids. We won't be devoting a large amount of time on metalloids in this text but we will mention some important aspects of them when relevant to other topics. Silicon for example appears lustrous, but is not malleable or ductile (it is brittle - a characteristic of some nonmetals). Oct 27, 2022 · These elements, called metalloids or sometimes semimetals, exhibit properties characteristic of both metals and nonmetals. Figure 4-9. Every element can be classified as either a metal, a nonmetal, or a metalloid (or semi metal). Jan 27, 2026 · Some metalloids, such as silicon and germanium, can act as electrical conductors under the right conditions, thus they are called semiconductors. Metalloids can also be called semimetals. Certain elemental properties become apparent in a survey of the periodic table as a whole. These elements, called metalloids or sometimes semimetals, exhibit properties characteristic of both metals and nonmetals. lhi1, cy12, seqg, cut0l, uhu, uy9, khfbo, vvzit7i, fstuibj, ak,
