double bond
This term is a technical specification used primarily in chemistry to describe a specific type of covalent linkage. It carries a neutral, descriptive tone and is used in both academic textbooks and professional laboratory settings to distinguish from single or triple bonds.
Because it refers to a specific structural feature of a molecule, it is used as a countable noun. One can discuss a single double bond within a molecule or multiple double bonds across a complex organic structure.
Meanings
