Verified by Experts3
(3) The number of radial nodes for an orbital with principal quantum number n and azimuthal quantum number 1 is given by the expression:
Number of radial nodes = n - 1 - 1
Using this expression, we can determine the number of radial nodes for each of the given atomic orbitals:
7s:n = 7,l = 0 7-0-1 = 6
7p:n = 7,l=l 7-1-1 = 5
6s:n = 6,l = 0 6-0-1 = 5
8p:n = 8,l=l 8-1-1 = 6
8d:n = 8,l = 2 8-2-1 = 5
Therefore, the atomic orbitals with 5 radial nodes are 7p, 6s, and 8d.
