由于不同种原子的相互结合，化合物才具有与组成该化合物的那些元素不同的特性。
The attachment of atoms of different kinds to each other is responsible for compounds having characteristic properties different from those of the elements of which they are made.
同位素是同一元素的不同种类，它们有着相同的化学特性但是原子重量不同。
Isotopes are different varieties of the same element, which have identical chemical properties but differ in atomic weight.
不属于同一种物质，但具有相同数目和相同种类原子的分子。
Molecules that have the same number and kinds of atoms but are different substances.
前言：同种中心原子的低氧化态无机含氧酸的氧化性比高氧化态的无机含氧酸的氧化性强，这是无机化学中普遍存在的一个问题。
In inorganic chemistry, there exists a common question: When the oxidation state of the same atom is increasing, its oxidizing is decreasing.
人们认为，不同种类的原子之间的差异，以及它们的不同组合方式，就构成了形形色色的物质。
The difference between the various kinds of atoms and the ways in which they were joined were supposed to result in the different kinds of matter.
道尔顿说：尽管人们知道数千种不同的化学物质，但这些物质仅仅是由少数不同种类的原子以一定的简单的方式结合在一起而组成的。
What Dalton said was that, although many thousands of different chemical substances are known, these are made up of only a few different kinds of atom combined together in definite simple ways.
