Question

Which of the following elements has the largest Van der Waals radii?

• A. Ne
• B. Cl
• C. O
• D. F

Answer 1

The correct option is B

Cl

Van der Waals radii is the internuclear distance between the two non-bonded atoms of a same element and it decreases from left to right and increases from top to bottom in the periodic table. $Ne$, $O$ and $F$ are in the second period, while $Cl$ is in the $3^{rd}$ period.
Therefore, chlorine has the largest Van der Waals radius when compared to $Ne$, $O$ and $F$.
