ÉTYMOLOGIE DU MOT SULPHUR
Soufre, from Old French, from Latin sulfur.
QUE SIGNIFIE SULPHUR EN ANGLAIS
Soufre
Le soufre ou le soufre est un élément chimique avec le symbole S et le numéro atomique 16. C'est un non-métal multivalent abondant. Dans des conditions normales, les atomes de soufre forment des molécules octatomiques cycliques avec la formule chimique S8. Le soufre élémentaire est un solide cristallin jaune clair à température ambiante. Chimiquement, le soufre peut réagir soit comme oxydant, soit comme agent réducteur. Il oxyde la plupart des métaux et plusieurs non-métaux, y compris le carbone, ce qui conduit à sa charge négative dans la plupart des composés organosulfurés, mais il réduit plusieurs oxydants forts, tels que l'oxygène et le fluor. Le soufre apparaît naturellement comme l'élément pur et comme sulfate et sulfate de minéraux. Les cristaux de soufre élémentaires sont communément recherchés par des collectionneurs de minéraux pour leurs différentes formes de polyèdre de couleurs vives. Étant abondant sous forme native, le soufre était connu dans les temps anciens, mentionné pour ses usages dans l'Inde ancienne, la Grèce antique, la Chine et l'Egypte. Les fumées provenant du soufre brûlant ont été utilisées comme fumigants, et des mélanges médicinaux contenant du soufre ont été utilisés comme baumes et antiparasitaires.
