Document Summary

Chm 115 - lecture 9 - quantum theory continued. Modeled the atom in a manner similar to that of the solar system. Electrons revolve around the nucleus in circular orbits. Each energy level is described by the principal quantum number (n) Principal quantum number indicates the distance of the electron from the nucleus. Indicates the amount of energy the electron has. Principal quantum number must be an integer. Principal quantum number must be at least 1. Electrons move between energy levels when they absorb and emit energy. When electrons absorb energy they move up energy levels. When electrons emit energy (in the form of photons) they move down energy levels. Energy of an electron at a certain energy level: en = -2. 18 * 10-18 j * 1/n2. Where n is the principal quantum number. Bohr"s planetary model only works for hydrogen or hydrogen like atoms (i. e. atoms with only one electron)
