Learning outcomes - after studying this topic, you should be able to:

• name the key experimental observations that led to the development of quantum mechanics
• convert between velocity, kinetic energy or momentum and wavelength of a free electron (or other particle of known mass)
• identify the components of the wave equation
• convert between the wavelength, frequency and energy of light
• calculate the allowed energy of a hydrogen-like atom of atomic number Z and quantum number n, and the wavelength of a transition between energy levels.
• appreciate how the wave nature of an electron leads to discrete energy levels

• Section 4.2 (in Blackman, Bottle, Schmid, Mocerino and Wille, Chemistry, 3^rd Edition, 2015 (John Wiley))

• Quantum mechanics (in ChemWiki)
