Question

a set of orbitals for which the quantum number l = 2 is
1.3 fold degenerate
2.5 fold degenerate
3.7 fold degenerate
4.not degenerate​

Answer 1

Answer:

2. 5 fold degenerate

Explanation:

Azimuthal Quantum ( l ) = 2 is for d subshell and d subshell had 5 orbital of equal energy

Answer 2

Answer:

5 fold degenerate asa set of orbitals for which the quantum number I=2

Explanation:

The set of orbitals for a given n and ℓ is called a subshell, denoted . The exponent y shows the number of electrons in the subshell. For example, the notation 2p4 indicates that the 2p subshell of an atom contains 4 electrons. This subshell has 3 orbitals, each with n = 2 and ℓ = 1.

The number of orbitals in a shell is the square of the principal quantum number: 12 = 1, 22 = 4, 32 = 9. There is one orbital in an s subshell (l = 0), three orbitals in a p subshell (l = 1), and five orbitals in a d subshell (l = 2). The number of orbitals in a subshell is therefore 2(l) + 1.
