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.
