... Based on Bohr’s model of the atom, we would be able to easily measure the radius of an element. • However, Bohr’s model of an atom was too simplistic and electrons are not fixed in orbit around nucleus. • They are found in orbitals (regions of space) where there is a high probability of finding an e ...
