A photoelectron spectrum of sodium excited with x-rays with an energy of 1254 eV shows two peaks at kinetics energies of 1190 eV and 1223 eV. These peaks are assigned to the sodium 2s and 2p electrons. What is the energy of the 2s electron in sodium?

Question

Quizplus · Accepted Answer

The energy of the 2s electron is calculated by subtracting the kinetic energy of the 2s electron (1190 eV) from the x-ray energy (1254 eV), resulting in -64 eV.
