Which of the following arrangements is correct regarding the three types of radii for an atom?

Options

  1. AMetallic radius < Covalent radius < Van der waal&#39;s radius
  2. BCovalent radius < Metallic radius < Van der waal&#39;s radius
  3. CVan der waal&#39;s radius < Metallic radius < Covalent radius
  4. DMetallic radius < Covalent radius > Van der waal&#39;s radius

Correct answer

B. Covalent radius < Metallic radius < Van der waal&#39;s radius

Step-by-step solution

The radii value are inversely related to the strength of bonds between the atoms. Covalent bonds are stronger than metallic while Van der waal&#39;s forces are the weakest.
