An earlier finding that the van der waals radii are related to their debroglie wavelengths for some non-metallic elements has been extended here toshow that in fact, they vary linearly with the ground state bohr radii for allthe elements of groups 1a to 8 a. Similarly, the valence shell radii and thecovalent radii are shown to be linearly dependent on the bohr radii. One tableof data and 5 figures have been provided here showing that all the above radiiare sums of two lengths, one of which is a multiple of the bohr radius and theother, a positive or negative constant for each group of elements.
