Mendeleev is the one who taught us that the properties of the elements are a function of the atomic mass.
门捷列夫教授我们元素特性,是元素质量所起的功能。
We have a table of the elements with properties varying periodically with atomic mass, so we compress all of that information and refer to it as the Periodic Table.
我们有一个元素表,其中的元素的特性,随着原子质量的改变而引起周期性的变化,所以我们将所有的信息精简,将它变成一个周期表。
Atoms of different elements have different weights and different chemical properties.
不同元素的原子的质量不同,化学特性也不相同。
