Formula and explanation
Formula: Eₙ = -(m_e e⁴)/(8 ε₀² h²) (Z²)/(n²) = -(13.6 eV)/(n²) Z² (for hydrogen atom, Z = 1 ). Applicable Conditions: Hydrogen atom or hydrogen-like ions (single-electron systems). Explanation: This formula gives the total energy (binding energy) of the electron in the n -th orbit. The negative sign indicates a bound state.
