The first person to propose the "atom"
1.All matter consists of invisible particles called atoms- composed all matter as tiny, solid spheres in various stages of motion
2. Atoms are indestructible- Atoms of an element cannot be created, destroyed, divided into smaller pieces, or transformed into atoms of another element.
3. Atoms are solid but invisible- the atom was a solid but could not be seen by the eye
4. Atoms are homogenous- no internal structure
5. Atoms differ in size, shape, mass, position, and arrangement-
->Solids are made of small, pointy atoms.
->Liquids are made of large, round atoms.
->Oils are made of very fine, small atoms that can easily slip past each other.
