The discussion revolves around the relationship between atomic mass and atomic radius, specifically comparing the atomic radius of helium isotopes He-3 and He-4. Participants are exploring how the atomic radius is defined and whether it varies between these isotopes.
There is a recognition that while the atomic radius may be considered the same for both isotopes, the nuclear radius differs. Some participants suggest that the ratio of atomic radii is 1, while others clarify the distinction between atomic and nuclear radii.
Participants are navigating the definitions of atomic and nuclear radii, and there is a reference to a formula related to nuclear radius that introduces additional complexity to the discussion.
so to make clear things the ratio of atomic radius is same but the nuclear radius isn't same right?ash64449 said:Nuclear radius will be different but atomic radius will remain the same. As atomic radius is the distance between the center of the nuclei to the outermost electron-which is same for both.
ratio is 1 and 'not same'
