    The Plum Pudding Model is that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.

    The Nuclear Model is what shows that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus in set, predictable paths.
  • Niels Bohr

    The Bohr (planetary) Model is basically electrons orbit the nucleus at set distances.
  • Erwin Schrodinger

    Erwin Schrodinger
    Quantum Mechanics Model is an atom with a tiny nucleus with probability waves instead of sharp orbits to describe the distribution of electrons, which have fuzzy positions but definite
