Answer :
The answer option which is an incorrect orbital notation is: C. 2d.
A sublevel refers to an energy level that is typically associated with the valence electrons found outside an atomic nucleus.
In Chemistry, there are four (4) main types of sublevel and these includes:
- s orbital (sublevel): 3s
- p orbital (sublevel): 2p
- d orbital (sublevel): 3d
- f orbital (sublevel): 4f
However, it is impossible for any atom of a chemical element to have a 2d orbital because electrons are generally located in the s and p orbitals (sublevels) in the second energy level.
