Question

The sizes and shapes of the hydrogen atom orbitals was revealed through graphical analysis of the corresponding wave functions. these wave functions also predict areas that the electrons have a zero probability of being found. these areas are known as nodes. nodes in the hydrogen atom orbitals exist either as spherical (radial) nodes or planar (angular) nodes. in the hydrogen atom, what is the total number of nodes present in a 5f orbital?

Answer 1

The total number of nodes = n-1. a) In your case for the 5 d orbital 5 - 1 = 4 nodes. b) The l quantum number for a d orbital is 2. Therefore you will have 2 angular (planar) nodes. c) You have 4 nodes, 2 of which are angular. Therefore, you will also have 2 radial nodes.
