CHM120H5 Lecture Notes - Lecture 4: Niels Bohr, Emission Spectrum, Centrifugal Force
Document Summary
Print out feedback forms from blackboard and bring to lab. Know the solution to the problem from last week as it is very representative for this kind of problem: Circular orbits of electrons around a central nucleus of protons. In physics, a standing or stationary wave is a wave that remains in a constant position. There can be an indefinite number of nodes in the closed distance of the wave. In a restricted system, the condition must be satisfied n must be an integer. The wave property of electrons means this applies to atoms. For a stable standing wave to apply, since the length of the wave must be the circumference. Why can electrons be placed in definite orbits around the nucleus? means that the electron can only take definite orbits and not any random orbit. We see different standing waves around the nucleus.
