Recall from Chapter 2 "that the probability of finding an electron in the various available orbitals falls off slowly as the distance from the nucleus increases. This point is illustrated in Figure 3.1.1 which shows a plot of total electron density for all occupied orbitals for three noble gases as a function of their distance from the nucleus.
