Question

Total energy of an electron of a hydrogen atom in the ground state is-
13.6 eV. What is the potential energy of the electron in the third orbit?​

Answer 1

Answer:

Total energy of Hydrogen atom in ground state is −13.6eV ,and potential energy is −27.2ev, Kinetic energy =13.6eV

For first excited state Kinetic energy = 3.4eV, Potential energy= −6.8eV, 

If potential energy of first excited energy is zero , Then for this we must add 6.8eV energy in system . We are just shifting the potential refrence.

So for ground state total energy =(13.6−27.2+6.8)=−6.8eV
