As an electron makes a transition from an excited State to the ground state of a hydrogen - like atom/ion :

A

Its kinetic energy increases but potential enegy and total energy decrease

B

kinetic energy potential energy and total energy decreases

C

kinetic energy decreases, potential energy increases but total energy remains same

D

kinetic energy and total energy decreases but potential energy increases

Text Solution

Verified by Experts

The correct Answer is:
A
`KE alpha (Z/n)^(2)`
as n decreases KE increases and TE, PE decreases.
