Document Summary
Chapter 6 part ii: electronic structure of atoms. De broglie"s hypothesis and heisenberg"s uncertainty principle set the stage for a new more broadly applicable theory at the atomic structure. There are many solutions to schrodinger"s wave function. Describes all the atoms/ elements in the universe. Each associated with a set of numbers called quantum numbers. That give us information about an electron occupying an atomic orbital. First quantum number, n: principle quantum number. The principle quantum number, n, can take on only integral values starting with 1: As n, increases, the orbital becomes larger and electron is farther from the nucleus. This means the electron has higher energy and is less tightly bound to the nucleus. Electron being further away, less tightly bound from nucleus. Second quantum number, l: angular momentum quantum; sublevels. Each principal quantum number includes one or more sublevels. The quantum numbers n and l are related:
