Problem

The ionization energy of sodium is 496 kJ/mol. In an experiment similar Hertz's experiment to which Einstein famously discovered the photoelectric effect, which statement below is true about the wavelength of radiation that could cause sodium to be ionized upon irradiation?

A. If sodium is irradiated with radiation with a wavelength greater than 496 nm, sodium can become ionized

B. If sodium is irradiated with radiation with a wavelength greater than 241 nm, sodium can become ionized

C. If sodium is irradiated with radiation with a wavelength lower than 496 nm, sodium can become ionized

D. If sodium is irradiated with radiation with a wavelength lower than 241 nm, sodium can become ionized

E. Since radiation is not a particle, no form of it may cause an electron to be ejected from sodium
