- Homework Statement
- For a neutral hydrogen atom where the ground state energy of the electron is taken as E=-13.6eV (with standard reference). Now if the potential energy of the first excited state is taken as zero reference potential energy then the potential energy of the third excited state is.
- Relevant Equations
- E=-13.6/n² where n is the orbit number.
Standard potential energy at infinity is zero.
I know how to solve this problem when the energy at ground state is zero but I don't know how to deal with 1st excited state energy as zero.
According to me since the potential energy is zero therefore the kinetic energy must be 13.6eV according to conservation of energy.
I also know that the energy is inversely proportional to the square of orbit number.
I don't know how to proceed further after this. Any kind of help or even a hint would be appreciated.
