Helloo!!
Third excited state n=4.
Energy of electron at third excited state= -13.6* Z^2/n^2 eV
= -13.6 x 4/16 eV= -3.4 eV
Energy at Ground state= -13.6 x 4/1
= -54.4 eV
Change= -3.4-(-54.4) eV= 51eV.
hope it helps!!

Answer:
How much energy would be required by an electron while moving from the ground state to the 3rd excited state of He+ Jon?
Explanation:
Therefore, the energy of the electron in the ground state is −13.6eV. Therefore, the energy required to move electrons from the ground state to the third excited state is 12.75eV.
3rd excited state means 4th orbit
Given-
He+ e- = 1st to 4 th (3rd excited state0
E= -13.6 Z2/n2
E3 = 1 = -13.6(2)2{1/(4)2-1/(1)2}
= -13.6 × 4{ 1/16-1}
= -13.6× 4 × -15/16.
E3 = 51 ev.
