O QUE SIGNIFICA HYDRIDE EM INGLÊS
Hidreto
Na química, um hidreto é o anião do hidrogênio, H- ou, mais comumente, é uma liga ou um composto no qual um ou mais centros de hidrogênio possuem propriedades nucleofílicas, reduzidas ou básicas. Em compostos que são considerados hidretos, o hidrogênio é ligado a um elemento ou grupo mais eletropositivo. Os compostos contendo hidrogénio ligados a metais ou metalóides também podem ser referidos como hidretos, mesmo que, neste caso, os centros de hidrogênio possam ter um caráter prótico. Quase todos os elementos formam compostos binários com hidrogênio, sendo as exceções He, Ne, Ar, Kr, Pm, Os, Ir, Rn, Fr, Ra.
definição de hydride no dicionário inglês
A definição de hidreto no dicionário é qualquer composto de hidrogênio com outro elemento, incluindo compostos iónicos tais como hidreto de sódio, compostos covalentes tais como o borano e os hidretos de metal de transição formados quando determinados metais, como o paládio, absorvem hidrogênio.
