SUMMARY
The maximum wavelength of light capable of removing electrons from rubidium is determined using the energy required to remove one mole of electrons, which is 208.4 kJ. This energy corresponds to 3.461e-19 J for a single electron. By applying the equation E = hc/lambda, where h is Planck's constant (6.626e-34 J·s) and c is the speed of light (2.9979e8 m/s), one can calculate the maximum wavelength of light necessary for this process.
