A hydrogen atom is in its second excited state, n = 3.

Using the Bohr model of hydrogen, find the linear momentum.

Using the Bohr model of hydrogen, find the angular momentum of the electron in this atom.

Expert Solution

r_n = n^2*a₀

a₀ = 0.0529nm

r_n = 9*(.0529) = .4761nm

a) p*r_n = n*h'

h'= plancks constant/(2*pi) = 1.055*10^-34

p = 3*h'/(.4761*10^-9) = 6.65*10^-25kg.m/sec

b) L = n*h'

L = 3*h' = 3.164*10^-34 j-sec

Answer the following questions using the Bohr model of the hydrogen atom. a) A hydrogen atom is the n = 3 excited state when its electron absorbs a photon of energy 4.40 eV. Draw a diagram roughly to scale, of relevant energy levels for this situation. Make sure to show and label the initial energy of the H atom in the n=3 state, the energy level at which this atom loses its electron, and kinetic energy of the electron. b)What...

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state. Classify the statements about this absorption and emission process as true or false. True On average, the electron is closer to the nucleus in the n = 4 state than in the n = 1 state. The wavelength of light absorbed when the electron is excited from the ground state to n = 4 is the same as the wavelength of...
