# Question

Assume that eight electrons are placed into the allowed energy levels of a cubic box where two electrons can occupy each allowed energy level. (See Exercise 148 for the appropriate energy equation.) Calculate the wavelength of light necessary to promote the highest-energy ground-state electron into the lowest- energy excited state assuming a cubic box with dimensions 1.50 nm × 1.50 nm × 1.50 nm.
