are 1.35, 1.34, 0.95 and 0.66

\mathop {\text{A}}\limits^{\text{o}}

respectively. The radius of the

Ne

atom is

View answer and explanation

Correct option: B

1.12\,\,\,\mathop {\text{A}}\limits^{\text{o}}

Option B (

1.12\,\,\,\mathop {\text{A}}\limits^{\text{o}}

) is correct because the ionic radius of Ne should be between the ionic radii of its isoelectronic neighbors, specifically smaller than F- and larger than Na+.
