An atom will have different radii depending on the bond it forms, so there is no fixed radius of an atom. Atomic Radii are therefore determined by the bonds they form.
The ambiguity of the underlying interpretation resides in the circumstance that the same value of 1.40 Å is assigned in the literature to the radius of the oxide anion, the water molecule, and the vdW radius of the oxygen atom. Table 12.1.9. Some radii (Å). Data are from ref.99 ...

Bohr radius definition and derivation - Introduction Bohr’s atomic model was a major breakthrough in the field of study of atomic structure. Atoms are a basic unit of all materials. According to the Bohr atomic model atoms contain a small central core c
