Atomic models

Limitation of the Plum Pudding model

had no nucleus

Merit of the Plum pudding model

Discovered Electrons

Merit of the Rutherford model (Planetary Model)

discovered the nucleus and proposed that atoms are mostly empty space. Also realized positive charges are in the nucleus of an atom

Limitation of the Rutherford Model (Planetary model)

Model failed to explain the stability of atoms(How electrons orbit the atom)

Merit of the Bohr Model

It explained that electrons lay on these things called orbitals

Limitations of the Bohr Model

Didn’t talk about it how electrons should emit energy and collapse into nucleus

Modern Atomic theory Merits

It includes the full structure of the atom including the protons, electrons, and neutrons.(Shows the electrons full orbit)
