CHEM 001A Lecture Notes - Lecture 20: Electron Configuration, Wave Function, Atomic Number
Document Summary
A node is where the wavefunction passes through 0 (i. e. changes sign from + to -), Shape is a function of angular momentum quantum number ( ) which dictates the and the probability of finding an electron is zero . angular nodes . Another kind of node - radial nodes. No angular nodes - a sphere - s orbital. One angular node - a dumbell - p orbital. A spherical region of wavefunction sign change and zero probability. Total nodes = angular nodes + radial nodes = n - 1. Radial nodes = n - - 1. Magnetic quantum number (m ) determines orientation (e. g. p x , p y , p z ) Not all spectra features explained by wave equations: Appearance of doublets in atoms with a single electron in outermost shell. Spinning of electron creates magnetic field oriented either up or down .
