Question
It takes 208.4 kJ of energy to remove 1 mole of electrons from 1 mole of atoms on the surface of rubidium metal. How much energy does it take to remove a single electron from an atom on the surface of solid rubidium in Joules?
What is the maximum wavelength of light capable of doing this in nanometers?
What is the maximum wavelength of light capable of doing this in nanometers?
Answers
208,400/6.022E23 = Energy/atom.
Eatom = hc/wavelength. Solve for wavelength, in meters, and convert to nm.
