Question

The energy of an electron in the first Bohr orbit of H atom is –13.6 eV. The possible energy value(s) of the excited state(s) for electrons in Bohr orbits of hydrogen is (are)
(a) –3.4 eV
(b) –4.2 eV
(c) –6.8 eV
(d) Both (a) and (c)

Answer 1

E is inversely proportional to n^2

therefore the answer will be (a)
