Calculate the energy of an electron in a specific energy level (n) of the Bohr model for hydrogen-like atoms. Energy levels become closer together as the principal quantum number increases.
Enter your values below
Energy level (1 = ground state)
1 for hydrogen, 2 for He⁺, etc.
How this calculator works
Energy at level n equals negative 13.6 eV times atomic number squared divided by principal quantum number squared.
