Formula and explanation
Formula: E n = - (m e e⁴)/(8 ₀² h²) (Z²)/(n²) = - (13.6)/(n²) Z² eV Applicable Conditions: Hydrogen atom or hydrogen - like ions (single - electron systems). Explanation: E n is the energy of the n - th stationary state, Z is the atomic number. The negative sign indicates the electron is bound. The ground state ( n = 1 ) has the lowest energy.
