The same type of atoms are identical and be combined to make compounds

- Atomic theory- what is it? How has it changed? who are the main scientists and their findings?
- Structure of an atom- what are the parts of an atom.

Then, Aristotle believed that all matter was Fire , Water, Air Ground and that matter had only four properties hot,cold,dry,wet. Next, Dalton he discussed that all atoms of a given element are exactly alike and atoms of different elements are different. Thompson was next, Thompson hinted that atom can be made of smaller particles and his theory was that atoms are made from a positively charged substance with negatively charged electrons like chips in a cookies. Rutherford theory was that atoms have a small, dense, positively charged center, which he called the “nucleus”. He said that nucleus is tiny compared to the atom as a whole, because the atom is mostly open space, like a cherry. Lastly, Bohr theorized that electrons move in definite orbits around the nucleus, much like planets circle the sun.
