In which of the following species, the ratio of s-electrons to p -electrons is same?
- A \(\mathrm{K}^{+}, \mathrm{Cr}^{3+}\)
- B \(\mathrm{Zn}, \mathrm{Fe}^{2+}\)
- C \(\mathrm{Zn}, \mathrm{Cr}^{3+}\)
- D \(\mathrm{Na}^{+}, \mathrm{K}^{+}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{K}^{+}, \mathrm{Cr}^{3+}\)
Step-by-step Solution
Detailed explanation
The ratio of s-elections and p-electron can be determined by electronic configuration. \(\mathrm{K}^{+}=1 \mathrm{~s}^2 2 \mathrm{~s}^2 2 \mathrm{p}^6 3 \mathrm{~s}^2 3 \mathrm{p}{ }^6\). The ratio of s electron to p-electron is \(6: 12\) which simplifies to \(1: 2\)…
