Formula and explanation
Formula: E n = - (R H)/(n²), where R H is the Rydberg constant (approximately 2.18 × 10⁻¹⁸ J ), and n is the principal quantum number ( n = 1, 2, 3, ). Applicable Conditions: Hydrogen atom or hydrogen - like ions (single - electron systems). Brief Explanation: This formula describes the energy of an electron in a specific orbit (energy level) of a hydrogen atom. The negative energy indicates the electron is bound to the nucleus. Larger n corresponds to higher energy (less negative) and greater distance from the nucleus.
