For a Hydrogen-like atom that has only one electron, the n=1 energy level which lies closest to the nucleus, is known as the [A] state. QUESTION 2 For a Hydrogen-like atom that has only one electron, any energy levei with n=2 or higher is known as an [A state. QUESTION 3 An [A] occurs when an electron in a higher energy level drops to a lewer energy level thereby releasing photons made from the difforence in energy between the levels. QUESTION 4 An (A) occurs when an electron in a lower enorgy level jumps up to a bigher energy level thereby absorbing photons made trom the differenon in energy between the levels
