1. that all elements have several isotopes.

2. that matter is composed of small indestructible particles.

3. that energy is neither created nor destroyed during a chemical reaction.

4. that an atom is predominantly empty space.

5. that the properties of matter are determined by the properties of atoms.

2. That matter is composed of small indestructible particles.

Explanation:

Dalton's atomic theory states:

• Matter is composed of atoms, which are the indestructible building blocks of matter and cannot be destroyed.

• All atoms of an element are identical.

• All atoms of different elements vary in size and mass.

• Compounds are produced through different whole number combinations of atoms.

• A chemical reaction is the rearrangement of atoms in the reactant and product compounds.
