Model 2 the nucleus is given by r R dr. The function 'R, is called the radial distribution function The probability of finding an electron between r andr + dr in a thin spherical shell centered at and is plotted for several states of hydrogen below, 10 PR²x1000 100 200 300 400 r(in pm) Critical Thinking Questions Sketch a plot of ² vs. r and a plot of R vs. r. What feature of the radial distribution plot results from the multiplication of these two functions? How do the radial distribution function 'R, and the probability density R² differ at small distances from the nucleus? What is significant about the radius at which the radial distribution function is a maximum?
