Chemistry-Atomic Radius
NEET Chemistry Atomic Radius MCQ Question
Type: MCQ-diagram based-Medium-Class 11
Consider a diagram that shows a covalent molecule where two atoms are bound by a single bond. If the bond distance is represented as 198 pm, what would be the atomic radius of each atom assuming they are identical?
A
99 pm
B
198 pm
C
396 pm
D
49.5 pm
Correct Answer
Option A
Detailed Explanation
The atomic radius of an atom in a covalent molecule can be estimated by taking half the bond distance between two atoms. Since the bond distance is 198 pm, half of this distance is 99 pm, which is the atomic radius of each atom.
