Visual diagram of a sp atomic orbitals

An s orbital and a p orbital are different atomic-orbital types. An sp hybrid orbital is a model formed by combining one s and one p orbital on an atom. The phrase s p diagram can therefore refer to more than one task.

Meaning and context

Introductory drawings show an s orbital as spherical and a p orbital with two lobes separated by a nodal plane. These shapes represent regions or surfaces associated with probability, not hard containers or paths followed by electrons.

Examples and usage

An sp hybridization model produces two hybrid orbitals oriented approximately 180° apart. Two unhybridized p orbitals remain available in the usual description. This is distinct from merely placing an s-orbital drawing beside a p-orbital drawing.

What to check

Check whether the problem asks for orbital shapes, electron filling, or hybridization. A text description cannot replace a required labeled diagram, but it can clarify what the diagram needs to distinguish. Avoid treating color conventions as physical charges or literal orbital walls.
