Both are correct.

Vedclass · Answer

(C) The atomic radius is defined based on the type of bonding between atoms. $1$. $Van \ der \ Waals$ radius is the distance between two non-bonded atoms in adjacent molecules,which is determined by weak $Van \ der \ Waals$ forces. $2$. Covalent radius is half the distance between the nuclei of two atoms bonded by a single covalent bond. Since covalent bonds are much stronger and involve electron sharing,the internuclear distance is shorter than in $Van \ der \ Waals$ interactions. Thus,$Van \ der \ Waals$ radius > covalent radius. $3$. Metallic radius is half the internuclear distance between two adjacent metal atoms in a metallic lattice. Metallic bonds are stronger than $Van \ der \ Waals$ forces,making metallic radii smaller than $Van \ der \ Waals$ radii. Therefore,both statements are correct.
