在十年前的化学书上,只知道化学元素最轻的一个是氢,最重的一个是铀。自从原子弹出现之后,方始知道铀后还有许多元素。原子弹本是由铀原子的变化而产生的,可以叫做铀原子弹。别的原子亦同样的会起变化,就可以有各种不同的原子弹;譬如氢原子起变化,即是氢原子弹了。氢因为是最轻,就以一为它的质量。原子量是一种相比量,当初就取各种元素与氢相比而得各种元素的原子量,并不是逐个原子实在的重量。物理学上注重原子的构造,曾以氢为造成一切物质的一种单体。在化学变化中,氢和别的元素化合时常有一个正价。从物理学家说来,即是氢在化合时于原子的外圈上失去一个(阴)电子,并且假定氢是最简单的原子,只有一个核和一个电子,去了电子,就剩下一个核,带着一单位的阳电荷,因为原子本是
In a chemistry book ten years ago, only one of the lightest chemical elements was hydrogen, the heaviest one was uranium. Since the atomic bomb appeared, Fang began to know that there are many elements behind uranium. The atomic bomb was originally produced by changes in uranium atoms, which can be called uranium atomic bombs. Other atoms also change in the same way, so that you can have different kinds of atomic bombs; for example, hydrogen atoms change, that is, hydrogen atoms bombs. Hydrogen is the lightest one, because of its quality. Atomic weight is a comparison, the original take all kinds of elements and hydrogen compared to the various elements of the atomic weight, not by atom by weight. Physics focuses on the structure of the atom, which used hydrogen as a monolith for everything. In chemical changes, hydrogen and other elements often have a combination of regular price. From the physicist’s point of view, hydrogen loses a (negative) electron from the outer ring of the atom when it is combined, and assuming that hydrogen is the simplest atom and that there is only one nucleus and one electron, going to the electron, leaving one Nuclear, with a unit of positive charge, because the atomic is
