\mathrm{N}

\mathrm{P}

covalent radius increases significantly but from

\mathrm{As}

\mathrm{Bi}

only a small increase is observed.
Reason (R): For a particular oxidation state covalent radii and ionic generally radii increases down the group.

View answer and explanation

Correct option: B

Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion

Option B is correct because both the assertion and the reason are true, but the reason does not explain the assertion. The small increase from As to Bi is due to the lanthanoid contraction.
