Study Notes
Development of Atomic Theory
- John Dalton developed the atomic theory based on his experiments and Democritus' ideas, paving the way for further discoveries on the inner structures of atoms.
Discovery of Subatomic Particles
- Joseph Thomson, Ernest Rutherford, and James Chadwick discovered the three main subatomic particles: electron, proton, and neutron, respectively.
Atomic Models
- Scientists created atomic models to show how atoms looked like, based on their assumptions about the atom's outer and inner appearances.
- Bohr's atomic model is the most well-known and widely used representation of the atom, featuring all subatomic particles in their proper places and electron shells around the nucleus.
- Bohr's model has been restructured over time to include representations of various shapes of atomic orbitals, following new discoveries about subatomic particles.
