Radius of atoms
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 model, … WebMar 17, 2024 · The radius of an atom measures 1–2 Å. Compared with the overall size of the atom, the nucleus is even more minute. It is in the same proportion to the atom as a marble is to a football field. In volume the …
