Atomic Theory and the Periodic Table · Atomic Structure

The Quantum Atom

An investigation into the transition from Bohr's model to the quantum mechanical model of the atom.

Key Questions

  1. 1How does the behavior of electrons in orbitals explain the emission spectra of different elements?
  2. 2What evidence do we have that electrons exist in specific energy levels rather than arbitrary paths?
  3. 3How does the structure of an atom determine its position on the periodic table?
