Mendeleyev [-1-] completed his studies and eventually landed a position at the local university. [---2---]

However, in 1869, at the age of 35, he began to [-3-] a way to arrange the elements. At the time, elements were normally grouped in two ways—either by atomic weight (using Avogadro's Principle) or by common properties (whether they were metals or gases, for instance). [-4-]

[-5-] , the principle had actually been [-6-] three years previously by an amateur chemist in England named John Newlands. He suggested that when elements were arranged by weight they appeared to repeat certain properties—[-7-]—at every 8th place along the scale. Slightly unwisely, [-8-] , Newlands called it the Law of Octaves and likened the arrangement to the octaves on a piano keyboard. Perhaps there was something in Newlands's manner of presentation, but the idea was considered [-9-] preposterous and widely mocked. At gatherings, droller members of the audience would sometimes ask him if he could get his elements to play them a little tune. [---10---]


dutifully There he was a competent but not terribly outstanding chemist, known more for his wild hair and beard, which he had trimmed just once a year, than for his gifts in the laboratory. toy with Mendeleyev's breakthrough was to see that the two could be combined in a single table. As is often the way in science anticipated in a sense to harmonize for this was an idea whose time had not quite yet come fundamentally Discouraged, Newlands gave up pushing the idea and soon dropped from view altogether.
門(mén)捷列夫兢兢業(yè)業(yè)地完成了學(xué)業(yè)，最后任職于當(dāng)?shù)氐囊凰髮W(xué)。他在那里是個(gè)稱(chēng)職的而又不很突出的化學(xué)家，更以他亂蓬蓬的頭發(fā)和胡子而不是以他在實(shí)驗(yàn)室里的才華知名。他的頭發(fā)和胡子每年只修剪一次。 然而，1869年，在他35歲的那一年，他開(kāi)始琢磨元素的排列方法。當(dāng)時(shí)，元素通常以?xún)煞N方法排列--要么按照原子量（使用阿伏伽德羅定律），要么按照普通的性質(zhì)（比如，是金屬還是氣體）。門(mén)捷列夫的創(chuàng)新在于，他發(fā)現(xiàn)二者可以合在一張表上。 　　實(shí)際上，門(mén)捷列夫的方法，3年以前一位名叫約翰?紐蘭茲的英格蘭業(yè)余化學(xué)家已經(jīng)提出過(guò)，這是科學(xué)上常有的事。紐蘭茲認(rèn)為，如果元素按照原子量來(lái)進(jìn)行排列，它們似乎依次每隔8個(gè)位置重復(fù)某些特點(diǎn)--從某種意義上說(shuō)，和諧一致。有點(diǎn)不大聰明的是--因?yàn)檫@么做時(shí)間還不成熟--紐蘭茲將其命名為"八度定律"，把這種安排比做鋼琴鍵盤(pán)上的八度音階。紐蘭茲的說(shuō)法也許有點(diǎn)道理，但這種做法被認(rèn)為是完全荒謬的，受到了眾人的嘲笑。在集會(huì)上，有的愛(ài)開(kāi)玩笑的聽(tīng)眾有時(shí)候會(huì)問(wèn)他，他能不能用他的元素來(lái)彈個(gè)小曲子。紐蘭茲灰心喪氣，沒(méi)有再研究下去，不久就銷(xiāo)聲匿跡了。
