Question

\\Select all of the following that are true of 3d orbitals. You may need to consult your textbook to recall some of this information. A) Since they are in the 4th period, the quantum number n must be 4. B) All 3d orbitals have quantum number n = 3. C) quantum number l can be 0, 1, or 2. D) quantum number l must be 2. E) quantum number ml can be -2, -1, 0, 1, or 2. F) quantum number ml can be only 0, 1, or 2. G) quantum number ml must be +2

Answer 1

Following that are true of 3d orbitals:

B) All 3d orbitals have quantum number n = 3.

D) quantum number l must be 2.

E) quantum number ml can be -2, -1, 0, 1, or 2.

d orbital has l = 2 and the azimuthal quantum number ml values = (2l+1) = 5 values.

They are -2, -1, 0, +1, +2.
