Democritus was an ancient Greek philosopher in the 5th century BC. He believed that if you were to break something and then break those pieces, over and over again, you would eventually get to a piece so small, it would be microscopic. He called these pieces “atomos”, the Latin word for indivisible. Democritus theorised that:
- All matter consists of invisible particles called atoms.
- Atoms are indestructible.
- Atoms are solid but invisible.
- Atoms are homogenous (of the same kind/alike).
- Atoms differ in size, size, shape, position and arrangement.
