When do I use E_n = −13.6 Z²/n² eV in Structure of Atom, and what does it mean?
energy of an electron in a hydrogen-like atom.
E_n = −13.6 Z²/n² eV — energy of an electron in a hydrogen-like atom. Use it when: single-electron (H-like) species. Always check the condition holds before plugging in numbers.
Key point
E_n = −13.6 Z²/n² eV
