Hydrog\u00e8ne<\/h3>\n

Avec un poids atomique standard d’environ 1,008, l’hydrog\u00e8ne est l’\u00e9l\u00e9ment le plus l\u00e9ger du tableau p\u00e9riodique.\u00a0Sa forme monoatomique (H) est la substance chimique la plus abondante de l’Univers, constituant environ 75 % de toute la masse baryonique.

Sodium<\/h3>\n

Le sodium est un m\u00e9tal mou, blanc argent\u00e9 et hautement r\u00e9actif.\u00a0Le sodium est un m\u00e9tal alcalin, appartenant au groupe 1 du tableau p\u00e9riodique, car il poss\u00e8de un seul \u00e9lectron dans sa coque externe qu’il donne facilement, cr\u00e9ant un atome charg\u00e9 positivement, le cation Na+.

Le sodium m\u00e9tallique est principalement utilis\u00e9 pour la production de borohydrure de sodium, d’azoture de sodium, d’indigo et de triph\u00e9nylphosphine.\u00a0Une utilisation autrefois courante \u00e9tait la fabrication de t\u00e9tra\u00e9thylplomb et de titane m\u00e9tallique;\u00a0en raison de l’abandon du TEL et des nouvelles m\u00e9thodes de production de titane.\u00a0Un courant \u00e9lectrique et de la vapeur de sodium se combinent pour former une lueur jaun\u00e2tre.\u00a0Ce principe est utilis\u00e9 pour la fabrication des lampes \u00e0 vapeur de sodium.\u00a0Le sodium est parfois utilis\u00e9 comme agent d’\u00e9change de chaleur dans les centrales nucl\u00e9aires.\u00a0Le sodium liquide est scell\u00e9 dans des tuyaux entourant le c\u0153ur du r\u00e9acteur.\u00a0La chaleur g\u00e9n\u00e9r\u00e9e est absorb\u00e9e par le sodium et forc\u00e9e \u00e0 travers les tuyaux dans un \u00e9changeur de chaleur qui peut \u00eatre utilis\u00e9 pour g\u00e9n\u00e9rer de l’\u00e9lectricit\u00e9.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
