WebFeb 20, 2024 · Bohr correctly proposed that the energy and radii of the orbits of electrons in atoms are quantized, with energy for transitions between orbits given by ΔE = hf = Ei − Ef, where ΔE is the change in energy between the initial and final orbits and hf is the energy of an absorbed or emitted photon. WebAug 7, 2014 · We also know the Bohr radius: a 0 = k e ⋅ ℏ 2 m e ⋅ e 2 ≈ 5, 29 ⋅ 10 − 11 m Therefore we can write and cancel: r = a 0 ℏ 2 k e ⋅ m e ⋅ e 2 = n 2 ℏ 2 M ⋅ k e ⋅ Z e 2 ∴ Z M m e = n 2 ∴ n = Z ⋅ 208 ≈ 25 The third part: The Rydberg Formula is given as 1 λ v a c = R Z 2 ( 1 n 1 2 − 1 n 2 2)
