When an electron moves from a higher to a lower energy level, it releases a quantum of energy, which is what it had to absorb in order to make the jump in the first place. Thiâ¦s quantum of energy is often released in the form of a photon, which is a discrete amount of light of a certain wavelength.
According to Bohr, the amount of energy needed to move an electron from one zone to another is a fixed, finite amount. These zones are known as energy levels (or sometimes called electron shells). At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons. At the next energy level, there are four orbitals; a 2s, 2p1, 2p2, and a 2p3. Each of these orbitals can hold 2 electrons, so a total of 8 electrons can be found at this level of energy.
