1 янв 1803 г. - Dalton's Atomic Theory
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
