## Chemistry: The Central Science (13th Edition)

3 important pieces of information can be obtained from the radial probability functions: - The number of peaks (the place where an electron is most likely to be found) is equal with the principal quantum number $n$. The outermost peak is larger than the innermost ones. - The number of nodes (the place where there is no chance to find an electron) is equal to $n-1$. - As $n$ increases, the size of the orbital increases as well. In detail, the electron density is more spread out, meaning that there is a greater probability of finding an electron further from the nucleus.
