Teach: Quantization (HL)

By quantizing the angular momentum of an electron in a hydrogen atom, we can derive the Bohr energy levels. But what does this mean, and how does it work? Aims Background and Considerations According to the course guide, students are expected to understand that the existence of quantized energy and orbits arise from the quantization of angular momentum in the Bohr model for hydrogen as given by mvr = nh/2π . This...
