Comprehension
The wave function for an atomic orbital of single electron atom or ion is
\[
\Psi(r, \theta, \phi)=\frac{2}{3}\left(\frac{\mathrm{Z}}{3 \mathrm{a}_{0}}\right)^{3 / 2}(1-\sigma)\left(12-8 \sigma+\sigma^{2}\right) \cdot \sigma \cdot e^{-\sigma / 2} \cdot \cos \theta
\]
- where \( \sigma=\left(\frac{2 \mathrm{Zr}}{\mathrm{na}_{0}}\right) \) and \( \mathrm{a}_{0}=0.529 \) A. All other parameters have their usual meaning.
- The atomic orbital should be:
(a) \( 4 \mathrm{p} \)
(b) \( 5 \mathrm{p} \)
(c) \( 5 \mathrm{~d} \)
(d) \( 5 \mathrm{f} \)
