Academics

The Bohr model of the hydrogen atom pictures the electron as a tiny particle moving in a circular orbit about a stationary proton. In the n = 4 orbit the distance from the proton to the electron is 8.46 10-10 m, and the linear speed of the electron is 5.45 105 m/s.

(a) What is the angular velocity of the electron?
