WebOne postulate of Bohr’s model is that the negative electron moves around the positive nucleus, but only at certain radii. We’ll number those radii in increasing order using n = 1, 2, 3…. where n is the quantum number. Our goal is to find an expression for radius as a function of the other fundamental properties of the atom. WebJun 20, 2015 · 1 Ry = e4me 8ϵ2 0h2 = 2.18 × 10 − 18 J. and this simplifies the allowed energies predicted by the Bohr model (Equation 7.4.17) as. En = − (2.18 × 10 − 18)Z2 n2 J = − Z2 n2 Ry. Hence, the energy of the electron in an atom also is quantized. Equation 7.4.18 gives the energies of the electronic states of the hydrogen atom.
