During lab, you observed an emission of green visible light from the Cu2 ion. The literature reports emission of blue visible light from the Cu ion. Choose the statement(s) below that best explain this data. (Select all that apply.) Increasing the effective nuclear charge on an ion results in the emission of higher frequency photons. Increasing the effective nuclear charge on an ion results in the emission of shorter wavelength photons. The Cu2 ion has a greater effective nuclear charge than the Cu ion. The Cu ion has a greater effective nuclear charge than the Cu2 ion. Increasing the effective nuclear charge on an ion results in energy levels that are closer together. There is no reasonable explanation.
