The energy of the nth orbit is given by En = -13.6 / n² eV. What is the energy of the 5th orbit?
Q1. The energy of the nth orbit is given by En = -13.6 / n² eV. What is the energy of the 5th orbit?
Answer: -0.544 eV
Explanation: Substitute n = 5 into En = -13.6 / n² eV to get E5 = -13.6 / 25 = -0.544 eV.
