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

For hydrogen and hydrogen like atomsEn=−13.6z2n2eV Un=2En=−27.2z2n2eV and  Kn=En=13.6z2n2eVFrom these three relations. can see that as n decreases, Kn will increase but En and Un will decrease.
