WebThe sub-energy levels are known as s, p, d, and f. Orbital number of the subshell For example, If n = 1, (n – 1) = (1–1) = 0 Therefore, the value of ‘l’ is 0. So, the sub-energy level is 1s. If n = 2, (n – 1) = (2–1) = 1. Therefore, the value of ‘l’ is 0, 1. So, the sub-energy levels are 2s, and 2p. If n = 3, (n – 1) = (3–1) = 2. WebSince the photons absorbed or emitted by electrons jumping between the n = 1 and n = 2 energy levels must have exactly 10.2 eV of energy, the light absorbed or emitted must have a definite wavelenghth.
