Which of the following orbit of `He^(+)` ion will have the same energy as that of second orbit of hydrogen atom?

A

n = 1

B

n = 2

C

n = 3

D

n = 4

Text Solution

Verified by Experts

The correct Answer is:
D
Since `E alpha-Z^(2)//n^(2)`, the orbit n = 4 of `He^(+)` will have the same energy as that of n = 2 of hydrogen atom.
