課文翻譯

The most basic building block of matter is an atom: the smallest unit of matter into which an element can be divided and still retain its chemical properties. The idea that all elements are made up of atoms is called the atomic theory. It is the most widely accepted scientific theory in chemistry. (For more information on the nature of atoms see Supplement 7,p.S32.)
