Formula and explanation
Formula: E n = - (R H)/(n²) Applicable Conditions: Hydrogen atom or hydrogen - like ions (single - electron systems). Explanation: E n is the energy of the level with principal quantum number n, R H is the Rydberg constant (approx. 2.18 × 10⁻¹⁸ J or 13.6 eV ). The negative sign indicates the electron is bound to the nucleus.
