Question

The correct order of radii of F- F-, O and O2- is (A) O2->F->F>O (B) F->O2->F>O (C) O2->O>F->F (D) O2->F->O>F

Radii of the given species vary in the order. O2->F->O>F The size of the anion is larger than their parent atom. Also, the more the nuclear charge, the lesser is the size.

Q. The correct order of radii of $F^{-} F^{-}, O$ and $O^{2 -}$ is

$O^{2 -} > F^{-} > F > O$

$F^{-} > O^{2 -} > F > O$

$O^{2 -} > O > F^{-} > F$

$O^{2 -} > F^{-} > O > F$

Radii of the given species vary in the order.
$O^{2 -} > F^{-} > O > F$
The size of the anion is larger than their parent atom. Also, the more the nuclear charge, the lesser is the size.

Q. The correct order of radii of F−F−,O and O2− is

O2−>F−>F>O

F−>O2−>F>O

O2−>O>F−>F

O2−>F−>O>F
