which element will form the ion with the largest ionic radius? a o b n c f
Answer
Explanation:
Step1: Consider ion - formation
O forms $O^{2 -}$, N forms $N^{3 -}$, F forms $F^{-}$. These are all isoelectronic (have the same number of electrons, 10 electrons in this case).
Step2: Apply the rule for isoelectronic ions
For isoelectronic ions, the ion with the smallest nuclear charge has the largest ionic radius. The nuclear charge of O is +8, N is +7, and F is +9. N has the smallest nuclear charge among them.
Answer:
N
