WebIn Bohr’s model, radius an of the orbit n is given by the formula an = h2n2 ε 0 /π 2, where ε 0 is the electric constant. As Bohr had noticed, the radius of the n = 1 orbit is approximately the same size as an atom. With his … WebThe volume of an atom is about 15 orders of magnitude larger than the volume of a nucleus. For uranium atom, the Van der Waals radius is about 186 pm = 1.86 ×10−10m. The Van der Waals radius, r w, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom.
