The energy of the electron in the first Bohr orbit is -13.6 eV. What is its energy in the second Bohr orbit?
Q1. The energy of the electron in the first Bohr orbit is -13.6 eV. What is its energy in the second Bohr orbit?
Answer: -3.4 eV
Explanation: Energy is proportional to 1/n^2; for n = 2, energy = -13.6/4 = -3.4 eV; option B is for n = √2.
