Atomic Structure Question 122

Question: The energy of an electron in the first Bohr orbit of $ H $ atom is $ -13.6eV $ . The possible energy value(s) of the excited state(s) for electrons in Bohr orbits to hydrogen is(are)

Options:

A) $ -3.4eV $

B) $ -4.2eV $

C) $ -6.8eV $

D) $ +6.8eV $

Show Answer

Answer:

Correct Answer: A

Solution:

Values of energy in the excited state $ =-\frac{13.6}{n^{2}}eV $

$ =\frac{-13.6}{4}=-3.4,eV $ in which $ n=2,,3,,4 $ etc.
