This model was the first to show a nucleus, consisting of a large positive mass. Electrons surround the nucleus but are not shown in distinct energy levels.

• The Rutherford Model of the atom

• The Thompson, or "Plum Pudding Model" of the atom

• The Electron Cloud model of the atom

• Democritus's model of the atom.

This model was developed after J.J. Thompson discovered electrons, a particle smaller than an atom. It shows electrons floating freely in a positive region.

• The Thompson, or "Plum Pudding Model" of the atom

• The Rutherford Model of the atom

• Democritus's model of the atom

• The Electron Cloud model of the atom

Ernest Rutherford discovered that atoms were mostly _________________. 

• negatively charged
• positively charged
• electrons
• empty space. 

This model added on to previous models by showing electrons existed at certain "energy levels". However it does not accurately show what those levels look like.

• The Bohr Model of the atom

• The Rutherford Model of the atom

• The Thomson, or "Plumb Pudding Model" of the atom

• The Electron Cloud Model of the atom made by Heisenberg
