Bohr orbits

Brink and Jones sections: Standing waves (quantization). Atom seen as positive nucleus with vibrating electron waves surrounding it. Schrödinger's equation calculates the energy of these waves and their shape and position- most probable region of movement of electrons called orbitals (talk about n=1,2 energy levels and spdf orbitals).
