Answer to Question #107061 in Physical Chemistry for Easwari

Question

Calculate the energy values of the electron in second and third orbits of hydrogen atom

Answer 1

for electron on the n-th orbit in hydrogen atom energy E is defined as:

E = -E_R/n²

where E_R = 13.6 eV is rydberg energy.

Energy of electron on the 2nd orbit is

E₂ = -13.6/4 = -3.40 eV

And for the 3rd orbit:

E₃ = -13.6/9 = 1.51 eV
