Question

Find the energy of electron in 2nd bhor orbit ?

Answer 1

------------------ HEY DEAR ---------------------

*************************************************************

HERE IS YOUR ANSWER....

AS WE KNOW,

ENERGY IN BOHR'S ORBIT  = -13.6 /(N^2)

N HERE IS THE NO. OF ORBITAL

SO, ENERGY = (-13.6/4)

                      => -3.4 ELECTRON -VOLT

HOPE IT HELPS YOU...

THANKS FOR GIVING ME CHANCE TO ANSWER..

MARK ME BRAINLIEST PLZ...

Answer 2

According Energy level diagram

The total enegry of electron in second orbit is

We know that E = -13.6/n^2 eV

For second orbit

E  = - 13.6/2^2eV

= - 3.4eV

= -
