The energy of the nth orbit of a hydrogen atom is -13.6/n^2 eV. What is the energy required to excite an electron from n=1 to n=3?
Q1. The energy of the nth orbit of a hydrogen atom is -13.6/n^2 eV. What is the energy required to excite an electron from n=1 to n=3?
Answer: 12.09 eV
Explanation: ΔE = E3 - E1 = (-1.51) - (-13.6) = 12.09 eV. Other options miscalculate energy differences.
