Question

The energy of an electron in the first Bohr orbit of H atom is $-13.6eV$. The possible energy values of the excited state for electron in Bohr orbit of hydrogen is :

• A. $-3.4eV$
• B. $-4.2eV$
• C. $-6.8eV$
• D. $46.8eV$

Answer 1

The correct option is A $-3.4eV$

Possible energy values of excited state of electron in Bohr's orbit are $-13.6eV,\frac{-13.6}{2^2}eV,\frac{-13.6}{3^2}eV$ etc and so on.

Hence, among the given options the correct option would be A.
