WebWith this convention, the different energy levels of a Hydrogen atom are given by the equation: where E0 = 13.6 eV ( 1 eV = 1.602×10-19 Joules) and n = 1,2,3… and so on so that the ground state has energy E1= -13.6 eV and the second energy level (the first excited state) has energy E2 = -13.6/4 eV = -3.4 eV. In the formulas for energy of electrons at various levels given below in an atom, the zero point for energy is set when the electron in question has completely left the atom, i.e. when the electron's principal quantum number n = ∞. When the electron is bound to the atom in any closer value of n, the electron's energy is lower and is considered negative. Assume there is one electron in a given atomic orbital in a hydrogen-like atom (ion). The energy o…

WebJul 14, 2024 · Updated on July 14, 2024. In chemistry, the principal energy level of an electron refers to the shell or orbital in which the electron is located relative to the atom's nucleus. This level is denoted by the principal quantum number n. The first element in a period of the periodic table introduces a new principal energy level. WebThe specific distances from the nucleus at which electrons are located became known as energy levels .
