The covalent radius is the smallest of all the radii because covalent bonds are formed due to overlapping of orbitals and there is penetration of one atom in another. The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. An atomic radius table is structurally different from the classic periodic table of elements. Played 0 times. SURVEY .
