a) Identify which element each spectrum corresponds to and explain your reasoning. (Hint: the height of each peak is proportional to the number of electrons in that group) b) Identify which orbital(s) the leftmost peak in each spectrum corresponds to. Explain why the navy peak has a larger binding energy than the magenta peak? c) Identify which orbital(s) the rightmost peak in each spectrum corresponds to. Explain why the rightmost navy peak has a slightly smaller binding energy than the leftmost magenta peak. (Hint: think about what makes an exception to the Aufbau principle.)
