Hydrogen, for example, exists as a dinuclear compound rather than a mononuclear atom. While we can measure the "size" of this dinuclear compound, the relationship between its "size" and the radius of the mononuclear atom is not obvious. Since we can't be precise, the meaning of the term atomic radius is necessarily fuzzy.
