Module 1 : Atomic Structure
Lecture 5 : Wave Functions and Charge Densities.
 
   Recap
   In this lecture you would have learnt the following
 

Summary

  In this lecture, you have been introduced to the pictorial representation of atomic orbitals of hydrogen like atoms. Plots of radial parts of the wavefunction and their squares as well as the radial probability densities have been shown as a function of r. The theta part of the wavefunction was plotted as a polar plot. The polar plot gives a good idea of the shapes of orbitals as well as the structures of their nodes. The charge density plots and the boundary surfaces of the orbitals give an idea of the variation of the probability density in space and the region in space wherein the probability of finding an electron is very large (say 99%).
