Solution

The correct option is B van der Waal's radius
The van der Waals radius is half of the distance between two similar atoms in separate molecules in a solid. The van der Waals radius represents the overall size of the atom which includes its valence shell in a nonbonded situation.

It is not possible to measure the atomic radius precisely since the electron cloud surrounding the atom does not have a sharp boundary. One practical approach to estimate the size of an atom of a non-metallic element is to measure the distance between two atoms when they are bound together by a single bond in a covalent molecule and then dividing by two. For metals, we define the term "metallic radius" which is taken as half the internuclear distance separating the metal cores in the metallic crystal. The van der Waal's radius represents the overall size of the atoms which includes its valence shell in a non bonded situation. It is the half of the distance between two similar atoms in separate molecules in a solid. The atomic radius decreases across a period and increases down the group. Generally, same trends are observed in case of ionic radius. The ionic radius of the species having the same number of electrons depends on the number of protons in their nuclei.
