which of the following is the atomic radius of chlorine if the internuclear distance between two chlorine atoms is 200 pm?\na 90 pm\nb 200 pm\nc 196 pm\nd 100 pm
Answer
Explanation:
Step1: Recall atomic - radius concept
The internuclear distance between two identical atoms is equal to twice the atomic radius. Let the atomic radius of chlorine be $r$. The internuclear distance $d$ between two chlorine atoms is given by $d = 2r$.
Step2: Solve for atomic radius
We know that $d=200$ pm. Rearranging the formula $d = 2r$ to solve for $r$, we get $r=\frac{d}{2}$. Substituting $d = 200$ pm into the formula, we have $r=\frac{200}{2}=100$ pm.
Answer:
D. 100 pm
