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

kinetic energy and total energy decrease but potential energy increases

its kinetic energy increase but potential energy and total energy decrease

As electron goes to ground state, total energy decreases.

TE = -KE

PE = 2TE

So, kinetic energy increases but potential energy and total energy decreases.
