The second ionisation energy of the following elements follows the order
- A \(\mathrm{Zn}>\mathrm{Cd} < \mathrm{Hg}\)
- B \(Z n>C d>H g\)
- C \(\mathrm{Cd}>\mathrm{Hg} < \mathrm{Zn}\)
- D \(\mathrm{Zn} < \mathrm{Cd} < \mathrm{Hg}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Zn}>\mathrm{Cd} < \mathrm{Hg}\)
Step-by-step Solution
Detailed explanation
Key Point For similar electronic configuration of outer most shell, size will decide the value of ionisation energy. More the size, lesser is the value of ionisation energy. Electronic configuration - IInd I.E \(\mathrm{Zn}^{+}\) ion…
