Problem 1: Determine the total number of nodes for the 7s, 4p and 6d
orbitals. Also determine the number of radial and angular nodes for
each.
Please see solutions
Problem 2: Calculate the finite value of r, in terms of ao, at which the node
occurs in the wavefunction of the 2s orbital of a hydrogen atom.

The same,
regardless of
n
where the
substitution,
Z=1 and n=1 has
been made, ao is
the 1st Bohr
radius, 53 pm.
Atomic number
(so hydrogen-like
atoms can be
treated)
