Highest energy level of an electron corr...

Highest energy level of an electron corresponds to `n= infty` and it has an energy of…….eV.

A

zero

B

`infty`

C

13.6

D

-13.6

Text Solution

Verified by Experts

The correct Answer is:
A

Because `E_n=-(mZ^2e^4)/(8 epsi_0^2 n^2 h^2) implies E_n prop (-1/n^2)`
`implies For n= infty, E_n=0`
