van der waal radius is greater than co valent radius because van der waal radius is the distance between the nucleus of two atoms of different compound whereas covalent radius is distance between nucleus of atoms of same compound.
Van der Waals radius of Carbon is 170 pm (170*10-12m)
Atomic radius (calculated or empirical): 145 pm Covalent radius: 139 pm Van der Waals radius: 217 pm 1 pm = 10-12 m (p is pico)
Helium has the smallest atomic radius among all the elements on the periodic table. This is because helium has a small number of electron shells and a strong nuclear attraction, which results in a compact atomic structure.
Yes, benzene dimers can interact via Van der Waals interactions due to the presence of temporary dipoles. These interactions are weak compared to covalent bonds but can contribute to the overall stability of the dimer.
yes
Van der Waals radius of Carbon is 170 pm (170*10-12m)
Van der Waals radii are larger than atomic radii because they include the space occupied by the electron clouds around the atom, which are not considered in atomic radii. Van der Waals radii are used to estimate the effective size of atoms when they are close to each other and experience van der Waals forces.
The other word for atomic radius includes the Van der Waals radius, ionic radius, and covalent radius. The atomic radius refers to half the distance between the nuclei of identical neighboring atoms in the solid form of an element.
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius

Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
First, the value of the atomic radius is not fixed, but depends on the definition you're using. Second, no element has an atomic radius as large as 152 nm. All atomic radii are about 1000 times smaller than that. Finally, assuming that you meant to say 152 pm, lithium has a metallic radus of 152 pm, oxygen has a van der Waals radius of 152 pm, and cobalt has a calculated atomic radius of 152 pm.
They are named after Johannes Diderik van der Waals who was the first to postulate about inter molecular forces
