What are the main points in Dalton's atomic theory?
|
1. "All matter is composed of tiny, indivisible particles called atoms".
2. "All atoms of a particular element are identical, but the atoms of one element differ from the atoms of any other element". 3. Atoms of different elements combine with each other in certain whole-number proportions to form compounds. 4. "In a chemical reaction, atoms are rearranged to form new compounds; they are not created, destroyed, or changed into atoms of any other element." (Page 56) |
