Document Summary
D is the answer you just count across the periodic table. D, potassium has the larger atomic radius (furthest down and closest to left side) Want to find number of photons given: 3. 0 mj/s, 1 minute, 670 nm. 1 minute ) = 180 mj (1 minute)( 1000 mj smallest wavelength has the greatest frequency, so if we calculate the frequency of the visible portion of the spectrum (400 nm to 700 nm) It has to be 335 nm or shorter in order for the photoelectric effect to happen (to eject the electron) so no, magnesium does not work visible light does not have enough energy to eject electrons from magnesium. This has to be excited state because it is not the lowest energy state the x subscript implies the electrons are on the same orbital (which is invalid in electron configuration)
