Whose idea is the planetary model of the atom with electrons orbiting the nucleus?

  1. J.J. Thomson
  2. Ernest Rutherford ✓
  3. Niels Bohr
  4. Erwin Schrödinger

Explanation

Ernest Rutherford created the planetary model in 1911. He discovered that electrons orbit around a central nucleus. This was like planets orbiting the sun.

J.J. Thomson had the plum pudding model. Niels Bohr improved Rutherford’s model with energy levels. Schrödinger created the quantum mechanical model later.

Remember: Rutherford’s gold foil experiment led him to discover the nucleus.
