Описание:

Dalton's Atomic Theory states:

1. The elements are made of atoms, which are tiny particles, too small to see.

2. All atoms of a particular element are identical.

3. Atoms of different elements have different
properties: their masses are different, and their chemical reactions are different.

4. Atoms cannot be created, destroyed, or split.

5. In a chemical reaction, atoms link to one another, or separate from one another
