Chemistry / Unit 5 Chem 0856 short lesson, about 20 seconds
Orbital Diagrams
Captions available
The idea
An orbital diagram represents each orbital as a box and each electron as an arrow, arrow direction showing spin, adding detail notation lacks.
In practice
Nitrogen's 2p diagram shows three boxes, each holding one upward arrow, matching Hund's rule.
Where people slip
Electron configuration notation cannot show which orbitals in a subshell hold unpaired electrons — only a diagram shows that.
