Problem

Ionization involves completely removing an electron from an atom. Light of a particular wavelength can cause ionization to occur if it has the required energy. The energy to ionize a certain element is 530 kJ/mol. What wavelength contains enough energy in a single photon to ionize one atom of this element? Enter your answer with three significant figures.

Solution
  • The equation for energy is:

  • Wavelength (λ) is related to frequency (v) by the equation:
