A chemical element (as boron, carbon, phosphorus, nitrogen, oxygen, sulfur, chlorine, or argon) that is not classed as a metal because it does not exhibit most of the typical metallic properties. 6, record 1, English, - nonmetal
Record number: 1, Textual support number: 1 CONT
Non-metals are the elements in groups 14-16 of the periodic table. Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon). The non-metals have no metallic luster, and do not reflect light. They have oxidation numbers of ±4, -3, and -2. The Non-Metal elements are: Hydrogen. Carbon. Nitrogen. Oxygen. Phosphorus. Sulfur. Selenium. 7, record 1, English, - nonmetal

An element that, in general, is characterized chemically by the ability to form anions, acidic oxides and acids, and stable compounds with hydrogen. 6, record 1, English, - nonmetal

Un non-métal est un élément chimique non métallique qui n'est ni un halogène, ni un gaz rare. Les non-métaux comprennent [...] les éléments suivants : [.] - hydrogène; - carbone; - azote; - oxygène; - phosphore; - soufre; - sélénium. 6, record 1, French, - non%2Dm%C3%A9tal
Record number: 1, Textual support number: 1 OBS
Les non-métaux s'opposent aux métaux d'abord par leurs propriétés physiques [...]. Au point de vue chimique, ce sont des éléments électronégatifs [et] leurs oxydes sont [...] acides ou neutres. 7, record 1, French, - non%2Dm%C3%A9tal
Record number: 1, Textual support number: 2 OBS
Les propriétés physiques des non-métaux les différencient nettement des métaux : ils conduisent mal l'électricité (conductivité électrique) et la chaleur (conductivité thermique); ils ne sont ni malléables, ni ductiles. [...] Les non-métaux forment généralement des liaisons ioniques avec les métaux. 6, record 1, French, - non%2Dm%C3%A9tal
Record number: 1, Textual support number: 3 OBS
Le tableau périodique des éléments était autrefois divisé en 3 groupes : les métaux, les semi-métaux, et les éléments non métalliques ou métalloïdes. Les éléments non métalliques comprenaient les non-métaux (listés ci-dessus), les halogènes et les gaz rares. 6, record 1, French, - non%2Dm%C3%A9tal
Record number: 1, Textual support number: 4 OBS
Aujourd'hui, on classe les éléments en métaux, semi-métaux et non-métaux. 8, record 1, French, - non%2Dm%C3%A9tal

Etimológicamente, metaloide significa semejante, parecido a los metales cuando en realidad es todo lo contrario. Por eso se tiende hoy a calificar a esos cuerpos de no metal o no-metal. 2, record 1, Spanish, - no%20metal
