O QUE SIGNIFICA RADON EM INGLÊS
Radônio
O radônio é um elemento químico com o símbolo Rn e o número atômico 86. É um gás nocivo radioativo, incolor, inodoro e insípido, que ocorre naturalmente como um produto indireto de decaimento do urânio ou do tório. Seu isótopo mais estável, 222Rn, tem uma meia-vida de 3.8 dias. O radônio é uma das substâncias mais densas que continua a ser um gás em condições normais. É também o único gás em condições normais que possui apenas isótopos radioativos e é considerado um risco para a saúde devido à sua radioatividade. A radioatividade intensa também prejudicou estudos químicos de radônio e apenas alguns compostos são conhecidos. O radônio é formado como um passo intermediário nas cadeias de decaimento radioativas normais, através das quais o tório e o urânio desaparecem lentamente em chumbo. O tório e o urânio são os dois elementos radioativos mais comuns na Terra; Eles estiveram por perto desde que a Terra se formou. Seus isótopos de ocorrência natural têm semi-vidas muito longas, na ordem dos bilhões de anos. O tório e o urânio, o seu radio do produto de decaimento e o seu radão do produto decadente, continuarão a ocorrer por dezenas de milhões de anos em quase as mesmas concentrações que agora.
definição de radon no dicionário inglês
A definição de radão no dicionário é um elemento radioativo incolor do grupo de gás raro, cujo isótopo mais estável, o radão-222, é um produto de decaimento do rádio. É usado como fonte de partículas alfa em radioterapia. Símbolo: Rn; número atômico: 86; meia-vida de 222Rn: 3,82 dias; valência: 0; densidade: 9,73 kg / m³; ponto de fusão: -71 ° C; Pb em ebulição: -61.7 ° C.
