The ionic radii of

L{i^ + },\,B{e^{ + 2}}

and

B{e^{ + 3}}

follow the order

View answer and explanation

Correct option: D

L{i^ + } > B{e^{ + 2}} > {B^{3 + }}

Option D (

L{i^ + } > B{e^{ + 2}} > {B^{3 + }}

) is correct because for isoelectronic ions, the ionic radius decreases with increasing nuclear charge.
