Potential energy is −27.2eV in second orbit of He+ then calculate, double of total energy in first excited state of hydrogen atom:-
Energy(Helium) =−13.6×4n2
PE=−2KE.
TE=PE×2=−27.222×2=−6.8eV
Hence,
option C is correct answer.
The energy of an electron in the first Bohr orbit of H atom is -13.6eV. The possible energy value(s) of the excited state(s) for electrons in Bohr orbits to hydrogen is(are)
