From Bohr to Quantum: Pinpointing Electron Locations

The Evolution of Atomic Models

• Dalton: Described atoms as small, spherical, indivisible particles.

• J.J. Thomson: Proposed the plum pudding model, where a whole atom was a positive sphere with tiny negative electrons embedded within.

• Rutherford: Discovered the nucleus (protons and neutrons) and stated that electrons existed outside the nucleus, with the atom being mostly empty space.

• Bohr: Introduced the concept of electrons occupying specific energy levels, but still lacked sufficient specificity on their exact location within those levels.

• Quantum Model: Aims to provide specific
