The correct order of atomic radii of N, F, Al, Si is
- A \(\mathrm{F}\gt\mathrm{N}\gt\mathrm{Si}\gt\mathrm{Al}\)
- B \(\mathrm{F}\gt\mathrm{N}\gt\mathrm{Al}\gt\mathrm{Si}\)
- C \(\mathrm{Al}\gt\mathrm{Si}\gt\mathrm{F}\gt\mathrm{N}\)
- D \(\mathrm{Al}\gt\mathrm{Si}\gt\mathrm{N}\gt\mathrm{F}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Al}\gt\mathrm{Si}\gt\mathrm{N}\gt\mathrm{F}\)
Step-by-step Solution
Detailed explanation
In periodic table, left to right atomic radii decreases and from top to bottom atomic radii increases. \(\therefore \quad \mathrm{Al}\gt\mathrm{Si}\gt\mathrm{N}\gt\mathrm{F}\)
