Which of the following options represents the correct ionic radii in \(Å^{\circ}\) of \(\mathrm{N}^{3-}, \mathrm{O}^{2-}\) and \(\mathrm{F}^{-}\), respectively?
- A 1.71, 1.36 and 1.40
- B 1.36, 1.40 and 1.71
- C 1.71, 1.40 and 1.36
- D 1.40, 1.36 and 1.71
Answer & Solution
Correct Answer
(C) 1.71, 1.40 and 1.36
Step-by-step Solution
Detailed explanation
Among isoelectronic species, greater the negative charge, greater will be the ionic radii. In anionic isoelectronic species there are more numbers of electrons than protons. These protons cannot attract all electrons to come closer. Thus, size of the ion increases. So, correct…
