Explain the differences between the Bohr model and the quantum mechanical model of the atom.

• The Bohr model is based on the idea of quantized energy levels and random orbits, while the quantum mechanical model describes the behavior of electrons as waves with no fixed position.

• The Bohr model is based on the idea of quantized energy levels and circular orbits, while the quantum mechanical model describes the behavior of electrons as both particles and waves, with their positions described by probability distributions.

• The Bohr model is based on the idea of continuous energy levels and elliptical orbits, while the quantum mechanical model describes the behavior of electrons as only particles with fixed positions.

• The Bohr model is based on the idea of quantized energy levels and spiral orbits, while the quantum mechanical model describes the behavior of electrons as particles with no wave-like properties.
