The number of atomic orbitals from the following having 5 radial nodes is 7 s ,   7 p ,   6 s ,   8 p ,   8 d

Correct answer

3

Step-by-step solution

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