  • The Commencement
  • Atom Models
  • John Dalton
  • J.J Thomson
  • The first Atom model to ever be discovered was in the year 1804. AS of today the last Atom model was dated back in the year1926
  • Ernest Rutherford
  • John Dalton was the first scientist to ever discover that atoms existed. He had came into conclusion that atoms make up all matter and that they are solid, like a bowling ball. He also came to find that they cannot be divided, destroyed or created.
  • Niels Bohr
  • In 1904, J.J Thomson did a Plum pudding,you can think of it as a chocolate chip cookie, where he found that the atom was composed of electrons. Thomson had them corpuscles.
  • Quantum Model
  • Ernest Rutherford had discovered the nucleus back in 1909, and found that their are positive charge in the center. He even found that atoms are mostly empty space. He had even done a gold foil experiment where found that every atom contains a nucleus where its positive charge and most of its mass are concentrated.
  • Now in1913,Niels Bohr had discovered that electrons orbit around the nucleus,based on the energy the elctron has. This is also the most popular atom to draw, its even still used today.
  • Now the last atom model, dated back in 1926. This is the Quantrum model. They came to find that electrons are in "Clouds" call orbitals. Their location is based on probability
