Which of the following is the energy of a possible excited state of hydrogen?
- −3.4 eV
- +6.8 eV
- +13.6 eV
- −6.8 eV
Correct answer: −3.4 eV
Solution
The energy of an excited state of hydrogen corresponds to a less negative value than the ground state energy of -13.6 eV, and -3.4 eV represents the energy level of the first excited state, indicating that the electron is further from the nucleus.
