If the electron in a hydrogen atom moves from ground state orbit to \(5^{\text {th }}\) orbit, then the potential energy of the electron
- A is increased
- B is zero
- C is decreased
- D remains unchanged
Answer & Solution
Correct Answer
(A) is increased
Step-by-step Solution
Detailed explanation
The potential energy of electron in hydrogen atom is given by
\(
\mathrm{U}=-\frac{1}{4 \pi \varepsilon_0} \cdot \frac{\mathrm{e}^2}{\mathrm{r}}
\)
Hence as \(r\) increase, potential energy will increase. (It will become less negative)
\(
\mathrm{U}=-\frac{1}{4 \pi \varepsilon_0} \cdot \frac{\mathrm{e}^2}{\mathrm{r}}
\)
Hence as \(r\) increase, potential energy will increase. (It will become less negative)
