Atomic Models

Atomic Models

1. Thompson Plum Cake Model: Positive and Negative Charge equally distributed

2. Rutherford Model

   • All the positive charge is concentrated in Nucleus
   • Most of the space inside the atom is empty
   • Positive charge of the atom or Nucleus occupies very little space as compared to the size of atoms

3. Bohr Energy Level Model

   • Protons and neutrons are in the nucleus
   • Electrons can only be certain distances from the nucleus
   • The electrons orbit the nucleus at fixed energy levels
   • The electrons must absorb or emit a fixed amount of energy to travel between stationary orbits
