Kinetic energy of the electron in second excited state of He + will be

1.	Kinetic energy of the electron in second excited state of He + will be?
Answer» ANSWER: -1.51ev Explanation: Energy=-13.6Z^2/n^2 so,E=-13.6*1/3^2 = -13.6/9 =-1.51ev.

Kinetic energy of the electron in second excited state of He + will be?

Answer»

-1.51ev

Explanation:

Energy=-13.6Z^2/n^2

so,E=-13.6*1/3^2

= -13.6/9

=-1.51ev.
