WAS BEDEUTET METALLOID AUF ENGLISCH
Metalloid
Ein Metalloid ist ein chemisches Element, das Eigenschaften zwischen den Metallen und Nichtmetallen hat. Es gibt keine Standarddefinition eines Metalloids, noch gibt es eine vollständige Übereinstimmung darüber, welche Elemente in geeigneter Weise als solche klassifiziert werden. Trotz dieser fehlenden Spezifität bleibt der Begriff in der Chemie-Literatur in Gebrauch. Die sechs allgemein anerkannten Metalloide sind Bor, Silicium, Germanium, Arsen, Antimon und Tellur. Elemente, die weniger allgemein als Metalloide erkannt werden, umfassen Kohlenstoff, Aluminium, Selen, Polonium und Astatine. Auf einem Standard-Periodensystem können alle diese Elemente in einem diagonalen Bereich des p-Blocks gefunden werden, der sich von Bor an einem Ende zu astatine an der anderen erstreckt. Einige Periodensysteme umfassen eine Trennlinie zwischen Metallen und Nichtmetallen, und es sind im allgemeinen die an diese Linie angrenzenden Elemente oder seltener ein oder mehrere der Elemente, die an diese Elemente angrenzen, die als Metalloide bezeichnet werden. Typische Metalloide haben ein metallisches Aussehen, aber sie sind spröde und nur faire Leiter von Elektrizität. Chemisch verhalten sie sich meist als Nichtmetalle. Sie können Legierungen mit Metallen bilden. Die meisten ihrer anderen physikalischen und chemischen Eigenschaften sind in der Natur vorbei.
Definition von metalloid im Wörterbuch Englisch
Die erste Definition von Metalloid im Wörterbuch ist ein nichtmetallisches Element wie Arsen oder Silizium, das einige der Eigenschaften eines Metalls aufweist. Andere Definition von Metalloid ist oder ist ein Metalloid. Metalloid ähnelt auch einem Metall.
