Soon after taking up his position, Davy began to [-1-]new elements one after another—potassium, sodium, magnesium, calcium, strontium, and aluminum or aluminium, [-2-] . The confusion over the aluminum/aluminium spelling arose because of some [-3-] indecisiveness on Davy's part. When he first isolated the element in 1808, he called it alumium. For some reason he thought better of that and changed it to aluminum four years later. [---4---]

He discovered so many elements not so much because he was serially astute as because he developed an ingenious technique of applying electricity to a molten substance—electrolysis, as it is known. Altogether he discovered [-5-] elements, a fifth of the known total of his day. [---6---] He grew so attached to the gas that he drew on it (literally) three or four times a day. Eventually, in 1829, [-7-]



bang out depending on which branch of English you favor uncharacteristic Americans dutifully adopted the new term, but many British users disliked aluminum, pointing out that it disrupted the -ium pattern established by sodium, calcium, and strontium, so they added a vowel and syllable. a dozen Davy might have done far more, but unfortunately as a young man he developed an abiding attachment to the buoyant pleasures of nitrous oxide. it is thought to have killed him.
上任不久，戴維開始宣布發(fā)現(xiàn)一種又一種新的元素：鉀、鈉、錳、鈣、鍶和鋁。 他發(fā)現(xiàn)那么多種元素，與其說是因?yàn)樗闱辶嗽氐呐帕?，不如說是因?yàn)樗l(fā)明了一項(xiàng)巧妙的技術(shù)：把電流通過一種熔融狀態(tài)的物質(zhì)--就是現(xiàn)在所謂的電解。他總共發(fā)現(xiàn)了12種元素，占他那個(gè)時(shí)代已知總數(shù)的五分之一。戴維本來會(huì)作出更大的成績(jī)，但不幸的是，他是個(gè)年輕人，漸漸沉迷于一氧化二氮所帶來的那種心曠神怡的樂趣。他簡(jiǎn)直離不開那種氣體，一天要吸入三四次．最后，在1829年，據(jù)認(rèn)為就是這種氣體斷送了他的性命。
