REFLECTION
Can you describe Rutherfordâs scattering experiment? Can you discuss the implications of Rutherfordâs scattering experiment for the structure of the atom? Can you explain how emission and absorption spectra are formed? Do you understand the concepts of energy levels and discrete energy? Do you understand what is meant by an atomic transition? Can you calculate the wavelength of the photon emitted in an atomic transition?

Do you appreciate the consequences of the Bohr quantisation condition for angular momentum?
