Question

Bohr model of doubly ionized lithium

Consider a Bohr model of doubly ionized lithium.
(a) Write an expression similar to En = -13.6 eV/n2 ? E2 = -13.6 eV/22 = -3.40 eV for the energy levels of the sole remaining electron. (Use the following asnecessary: n.)
En = eV

(b) Find the energy corresponding to n = 8.

Your response differs from the correct answer by more than 10%. Double check your calculations. eV

(c) Find the energy corresponding to n = 2.
eV

(d) Calculate the energy of the photon emitted when the electron transits from the eighth energy level to the second energy level. Express the answer both in electronvolts and in joules.
eV
J

(e) Find the frequency and wavelength of the emitted photon.
Hz
nm

(f) In what part of the spectrum is the emitted light?
