r_max =             P(r)_max =         
n = 1, l = 0   P(r) = r² { 2 e^-r }²  
n = 2, l = 0   P(r) = r² { (1 - r/2) e^-r/2 / sqrt(2) }² 
n = 2, l = 1   P(r) = r² { r e^-r/2 / sqrt(24) }²
n = 3, l = 0   P(r) = r² { 2/sqrt(27) (1 - 2r/3 + 2r²/27) e^-r/3 }²
n = 3, l = 1   P(r) = r² { 8/(27 sqrt(6)) r (1 - r/6) e^-r/3 }²
n = 3, l = 2   P(r) = r² { 4/(81 sqrt(30)) r² e^-r/3 }² 

Instructions: First click on Plot P10. Then plot any other probability. If you click on P10 before clicking another button you will see all plots simultaneously. Use "Set r Scale" and "Set P(r) Scale" for the n = 2 and 3 states. Place cursor on graph and press left mouse button to read coordinates. Press right mouse button to copy graph to a new window.
Note:  All distances are in units of Bohr radii, 
a₀ = 0.529 nm
