AP EAMCET · Chemistry · Structure of Atom
The correct order of atomic radii of the elements \(\mathrm{O}, \mathrm{N}, \mathrm{S}\) and \(\mathrm{P}\) is
- A \(\mathrm{N} < \mathrm{P} < \mathrm{S} < \mathrm{O}\)
- B \(\mathrm{N} < \mathrm{O} < \mathrm{P} < \mathrm{S}\)
- C \(\mathrm{O} < \mathrm{N} < \mathrm{P} < \mathrm{S}\)
- D \(O < N < S < P\)
Answer & Solution
Correct Answer
(D) \(O < N < S < P\)
Step-by-step Solution
Detailed explanation
The atomic size decreases on moving from left to right in a period as the number of valence electrons in the same shell increases due to which the effective nuclear charge increases. Thus, size of \(\mathrm{O}\) is less than \(\mathrm{N}\) and also size of \(\mathrm{S}\) is less…
