Given the radial wavefunction for a 2s atomic orbital shown
below, determine the finite value of r, in terms of
a0, at which the radial node occurs in the 2s
wavefunction of Li2+. Enter only the
numeric portion of your answer (to three decimal places) in the
space provided; do not enter the units (which will
be a0). In this equation, Z is the
atomic number, n is the principal quantum number,
and
.
