Problem- an electron in a hydrogen atom has orbital quantum, Ask an Expert

Academics

Problem- An electron in a hydrogen atom has orbital quantum numbers n = 2 and l = 1. Calculate the energy E, and give the degeneracy of this electron state. If you could define and illustrate the math that would be great

a. E= -1.09 x 10^-18 J, 3-fold degenerate

b. E = -5.45 x10^ -19 J, 3-fold degenerate

c. E= -1.09 x 10^-18 J, 2-fold degenerate

d. E = -5.45 x10^ -19 J, not degenerate

Please answer only if you are 100% confident
