The Planck relation [1] [2] [3] (referred to as Planck's energy–frequency relation, [4] the Planck–Einstein relation, [5] Planck equation, [6] and Planck formula, [7] though the latter might also refer to Planck's law [8] [9]) is a fundamental equation in quantum mechanics which states that the energy of a photon, E, known ... WebThe principal quantum numbers are sometimes known as these integers. The orbital energy in which an electron is placed is given by: E n = − R h 1/ n 2. Where, RH is called the Rydberg constant whose value is 2.18×10 –18 J. When an electron is far from the nucleus' impact, its energy is assumed to be zero.
