what is covalent radius and van der waals radius? don't use the language which is given in ncert. answer in simple words

Answer 1

Covalent radius is the intermolecular distance between the centres of two Covalent bonded atoms.

We can't take the same for noble gases because they don't react so easily

Thus van der waals radius is defined for noble gases.

It is the intermolecular distance between the centres of two noble gases.
