Final answer:
During the electron's transition from a higher to a lower energy level, it most likely released energy, possibly in the form of light, consistent with Bohr's model of the atom.
Step-by-step explanation:
When an electron moves from a higher energy level to a lower energy level, it most likely emitted energy. This concept is grounded in Bohr's model of the atom where each electron orbit is an energy level with a specific energy value. A transition between these levels involves a change in the electron's energy, corresponding to the energy difference between the levels.
For example, if an electron moves from level 8 to level 1, it descends through several energy levels and, according to Bohr's model, emits energy at each transition. This energy can be quantified, such as in the change of -10.2 eV from a higher to a lower state, releasing 10.2 eV of energy. The emitted energy often manifests as light, with the color depending on the energy change involved.
