WebBohr assumed that the electron orbiting the nucleus would not normally emit any radiation (the stationary state hypothesis), but it would emit or absorb a photon if it moved to a different orbit. The energy absorbed or emitted would reflect differences in the orbital energies according to this equation: ∣ Δ E ∣ = ∣ E f − E i ∣ = h ν = h c λ WebSolution From Example 12.3 we know that velocity of electron moving around a proton in hydrogen atom in an orbit of radius 5.3 × 10 –11 m is 2.2 × 10 –6 m/s. ...
