41. Compare qualitatively the first and second ionisation potentials of copper and zinc. Explain the observation.
(1996, 2M
Show Answer
Solution:
- $\mathrm{Zn}=3 d^{10} 4 s^{2}, \mathrm{Cu}=3 d^{10} 4 s^{1}$ The first ionisation energy is greater for $\mathrm{Zn}$ but reverse is true for 2nd ionisation energy.
