Question

Atomic radii of fluorine and neon in Angstorm units are respectively given by:

• A. $0.72,1.60$
• B. $1.60,1.60$
• C. $0.72,0.72$
• D. none of these values

Answer 1

The correct option is A $0.72,1.60$

$Ne$ is slightly bigger than $F$ as $Ne$ is inert has completely filled electronic configuration. Thus is stable and hence has a slightly bigger size than $F$ which is the most electronegative element.
