Chemistry / Unit 5 Chem 0838 short lesson, about 20 seconds
The d and f Orbitals
Captions available
The idea
d orbitals, l = 2, and f orbitals, l = 3, have more complex, multi-lobed regions than s or p, with more nodes as l rises.
In practice
A d subshell holds five orbitals; f holds seven, each set by an ml value.
Where people slip
d and f orbitals' lobe count follows the nodal pattern s and p show — no new rule.
