John Dalton

Came Up Atomic Theory

John Daltons major contribution to atomic Theory is that there are many different types of atoms.

This theory explains several concepts that are relevant in the observable world: the composition of a pure gold necklace, what makes the pure gold necklace different than a pure silver necklace, and what occurs when pure gold is mixed with pure copper.

1. All matter is made of atoms. Atoms are invisible and indestructible.

2. All atoms of a given element are identical in mass and properties.

3. Compounds are formed by a combination of two or more different kinds of atoms.

4. A chemical reaction is a rearrangement of atoms.
