instead of any direction r . 2. Radial Distribution Function : 4 π r 2 Ψ 2 vs. r This shows the probability of finding the electron within a vanishingly thin spherical shell with a radius of r from the nucleus. Going out from the nucleus, this shows the variation in probability on the surface of increasingly larger spherical shells. 3. Electron Charge Cloud (Electron Density) Diagram This is a three-dimensional picture of Ψ 2 in which higher probability is rendered by darker shading or stippling. Most of such diagrams are meant to show approximately 90-99% of the total probability. 4. Contour Diagram This is a two-dimensional cross section (slice) through the probability distribution. Lines on the drawing connect regions of equal probability, much like isobars on a weather map connect regions of equal pressure. 5. Boundary Surface Diagram This is a three-dimensional solid model (or a picture of such a model) constructed so as to represent a surface that encloses approximately 90- 99% of the total probability. These are sometimes called "balloon models".

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
