Answer 1

1) all matter is composed of atoms

2) all atoms of the same element are identical

3) all atoms of different elements are different

4) atoms cannot be destroyed, subdivided, or created

5)Law of Multiple Proportions - In chemical reactions, atoms are combined, separated, or rearranged in simple whole number ratios

Answer 2

1. Atoms of different elements have different weights

2. Atoms are never created or destroyed, only re-arranged

3. Atoms in a given compound always have the same smallest whole number ratio

The Law of Constant Composition

Answer 3

In 1802, John Dalton stated his Atomic Theory; these are the five characteristics of atoms he had discovered:

1. Matter is made of individual and indivisible atoms.
2. All atoms of a given element are identical in their physical and chemical properties.
3. Atoms of different elements differ in their physical and chemical properties.
4. Atoms of different elements combine in simple whole number ratios (Also Dalton's Law of Definite Composition).
5. Chemical reactions involve the rearrangement of atoms.
