The energy of the electron in the third ...

The energy of the electron in the third orbit of H-atom is -1.51 eV. The energy of the electron in first orbit is

A

`-13.6` eV

B

`-16.6 ` eV

C

`-1.36` eV

D

13.6 eV

Text Solution

Verified by Experts

The correct Answer is:
A
`E_(n)=E_(1)/n^(2)`
`E_(3)=E_(1)/9`
`:. E_(1)=9 E_(3) =-9xx1.51=-13.6 eV`.
