Select the correct quantum numbers for the highlighted electrons in a set of 5d orbitals.
A
n = 5, l = 3, ml = – 4, ms = +1/2
B
n = 4, l = 4, ml = +1, ms = +1/2
C
n = 5, l = 2, ml = +1, ms = +1/2
D
n = 5, l = 5, ml = – 2, ms = +1/2
E
n = 5, l = 2, ml = +5, ms = +1/2
Verified step by step guidance1
Identify the principal quantum number (n) for the 5d orbitals. The principal quantum number n = 5 for 5d orbitals.
Determine the azimuthal quantum number (l) for d orbitals. The azimuthal quantum number l = 2 for d orbitals.
Examine the image to identify the magnetic quantum number (ml) for the highlighted electron. The highlighted electron is in the +1 orbital, so ml = +1.
Determine the spin quantum number (ms) for the highlighted electron. The electron is represented with an upward arrow, indicating ms = +1/2.
Combine the quantum numbers to describe the highlighted electron: n = 5, l = 2, ml = +1, ms = +1/2.
