IB Physics Topic 7.1 & 7.2: Discrete energy and radioactivity & nuclear reactions - Part 1

This video starts by introducing the progression of atomic models from Democritus to Bohr. It then discusses electron energy levels on the basis of absorption and emission spectra. After this, atomic structure is discussed, including the forces and notation before finishing with the concept of nuclides.
