WebJan 18, 2015 · Thus, if you want to measure an atom's radius, you have to measure the distance between two nuclei, and then divide it by two. This results in different types of … WebThis would just be q, v, times B, times one. Well, force is equal to mass times acceleration. So, Newton's second law. We know the ion is moving in a circular path, so this would be the centripetal acceleration. We have q,v, B, is equal to mass times the centripetal acceleration. q, v, B, is equal to the mass.

WebAs per the principle, we determine the radius based on the distance between the nuclei of two bonded atoms. An atom will have different radii depending on the bond it forms, so there is no fixed radius of an atom. The radii of atoms are therefore determined by the bonds they form.
