... Why do atoms exhibit discontinuous (line) spectra when they emit light? Why can’t an atom emit any wavelength of light? Energy is quantized. Emission is due to specific transitions between ground and excited states. 18. Refer to the activity series in chapter 10. For the single replacement reactions ...
