What is the correct order with respect to metallic property of \(\mathrm{Zr}, \mathrm{Cd}, \mathrm{Sn}, \mathrm{Sr}\) ?
- A \(\mathrm{Sn} < \mathrm{Cd} < \mathrm{Zr} < \mathrm{Sr}\)
- B \(\mathrm{Sn} < \mathrm{Sr} < \mathrm{Cd} < \mathrm{Zr}\)
- C \(\mathrm{Cd} < \mathrm{Zr} < \mathrm{Sr} < \mathrm{Sn}\)
- D \(\mathrm{Zr} < \mathrm{Sr} < \mathrm{Cd} < \mathrm{Sn}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{Sn} < \mathrm{Cd} < \mathrm{Zr} < \mathrm{Sr}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{Zr}, \mathrm{Cd}, \mathrm{Sn}, \mathrm{Sr}\) belong the \(5^{\text {th }}\) period and their order of arrangement from left to right is \(\mathrm{Sr}, \mathrm{Zr}, \mathrm{Cd}, \mathrm{Sn}\). Metallic property goes on decreasing as we move from left to right.…
