Which of the following arrangements is correct regarding the three types of radii for an atom?
- A Metallic radius < Covalent radius < Van der waal's radius
- B Covalent radius < Metallic radius < Van der waal's radius
- C Van der waal's radius < Metallic radius < Covalent radius
- D Metallic radius < Covalent radius > Van der waal's radius
Answer & Solution
Correct Answer
(B) Covalent radius < Metallic radius < Van der waal's radius
Step-by-step Solution
Detailed explanation
The radii value are inversely related to the strength of bonds between the atoms. Covalent bonds are stronger than metallic while Van der waal's forces are the weakest.
