The electron in a hydrogen atom makes a transition from an excited state to the ground state. Which of the following statements is true?

A

Its kinetic energy increases and its potential and total energies decrease

B

Its kinetic energy decrease , potential energy increases and its total energy

C

Its kinetic and total energies decrease and its potential energy increases

D

Its kinetic ,potential and total energies decrease

Text Solution

Verified by Experts

The correct Answer is:
A
Total energy `(E_(n)) = -13.6 (Z^(2))/(n^(2))eV `
`KE = - E_(n) and PE = 2E_(n)`
Since , n decrease , KE `uarr` and PE `darr, E_(n) uarr` .
