Webc. F2 In the Bohr model of the hydrogen atom, the electron occupies distinct energy states. One transition between energy states of the hydrogen atom is represented by the picture below. In this transition, n=∞------ n=4------- n=3---I n=2---I n=1---↓ a. The electron moves closer to the nucleus and energy is emitted b. WebΔ H for a reaction in one direction is equal in magnitude and opposite in sign to Δ H for the reaction in the reverse direction.
