当一百五十年以前化学还很不发达的时候,因为元素种类繁多,性质复杂,并且各种化合物的构成也是千变万化,人们感觉学习化学不是一件容易的事。1815年英国有一位医生,名叫普劳特(Prout)最先提出一切元素都是由氢原子构成的说法,后来,有很多人反对,又经过了很多年,到同位素发见以后哈肯斯(Harkins)又重新提起普劳特的主张,并且加以补充,他说:“元素都是氢与氦的原子组成的。”

When chemistry was still underdeveloped a hundred and fifty years ago, because of the variety of elements, the complex nature, and the composition of various compounds, people felt that learning chemistry was not an easy task. In 1815, a British doctor named Prout first proposed that all elements were made up of hydrogen atoms. Later, many people opposed it, and after many years, after the discovery of isotopes, Hackens (Harkins) renewed Proutt’s claim and added it, saying: “The elements are made up of atoms of hydrogen and helium.”
