a.The number of nodal spheres in the 6swave function.
b.The number of nodal spheres in a 6pwave function.
c.The number of nodal planes containing the z axis in
the real part of theψ 6 d 0 (ψ 620 ) wave function.
d.The number of nodal cones in the real part of theψ 6 p 1
(ψ 611 ) wave function.

18.32Identify the following statements as either true or false. If
a statement is true only under special circumstances, label
it as false.
a.Electrons in a multielectron atom move exactly like
electrons in a hydrogen-like atom with the appropriate
nuclear charge.


b.The correct wave function for a multielectron atom can
be written as an antisymmetrized product of orbitals.
c.If a helium atom is not confined in any container, the
center of mass of the atom moves exactly like a free
particle.
d.The orbital regions for a He+ion are approximately
the same size as those of a hydrogen atom.
e.The orbital regions of a He+ion have one-eighth
the volume of the orbital regions of a hydrogen
atom.
