Question

Which of the following sets of quantum number for orbitals in hydrogen atom has a greater energy of electrons?
a. n =3, l=2 and m = +1

b. n= 3, l=2 and m= -1

• A. a
• B. b
• C. Both have equal
• D. we cant calculate energy.

Answer 1

The correct option is C Both have equal

Both sets represents 3d sub-level whose each d orbital has the same energy, i.e d orbitals are degenerate.Therefore, both(a) and (b) are equal in energy.
