# Problem: With reference to the figure below, what is the relationship between the number of nodes in an s orbital and the value of the principal quantum number?Radial probability functions for the 1s, 2s, and 3s orbitals of hydrogen. These plots show the probability of finding the electron as a function of distance from the nucleus. As  n  increases, the most likely distance at which to find the electron (the highest peak) moves farther from the nucleus.
