When 58.4 nm radiation from a helium discharge lamp is directed on a sample of krypton, electrons
Question:
When 58.4 nm radiation from a helium discharge lamp is directed on a sample of krypton, electrons are ejected with a velocity of 1.59 × 106 m s−1. The same radiation ejects electrons from Rb atoms with a velocity of 2.45 × 106 m s−1. What are the ionization energies (in electronvolts, eV) of the two elements?
