Why is silicon used extensively in electronics? The metalloids in this list include boron, silicon and tellurium. Boron is neither a metal nor a nonmetal; instead, it is classified as a metalloid or a semimetal. Who is the actor in the Capital One commercial that plays Santa Claus? List two uses for each of these metalloids. Boron occurs sparsely, probably because bombardment by the subatomic particles produced from natural radioactivity disrupts its nuclei. It behaves as a nonmetal in reaction with sodium and a metal when combined with fluorine. All Rights Reserved. It touches the metalloid "staircase" on the periodic table. A metalloid is an element that displays properties of both metals and non metals. More frustrating is the choice “none of the above.” You feel very uncertain checking that possibility. On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids. Does a 1981 Datsun King Cab have seat belts for the jump seats?
