CH 301 Chapter Notes - Chapter LE10: Principal Quantum Number
Document Summary
Wave function: mathematical function that describes the system of interest. Can help to understand the spatial extent of the system and tells us where the electron is. Energy: every wave function has a particular energy. Degenerate solutions: many solutions with the same energy. Schrodinger equation: solve to get all the wave functions that will describe electron energy levels. One-electron system has 3 quantum numbers: principal quantum number (n): distance from the nucleus. Number is related to the energy associated with wave function. More stable energies are close to nucleus, must all be negative. Energy of a level: en= 2. 18 10 18(z2/n2: angular momentum quantum number (l): shape. An integer and can have any value starting at zero and going up to n -1: magnetic quantum number (ml): orientation in space. Number of degenerate solutions is equal to 2l+1. Orbital notations: describe the wave function for a hydrogen atom. Use the world orbital rather than wave function.
