Naming Binary Molecular Compounds
Captions available
The idea
A binary molecular compound is named with the more metallic element first, the nonmetallic element second and ending in -ide, each carrying a prefix.
In practice
SF6 is named sulfur hexafluoride: sulfur first with no prefix needed, fluorine second with the hexa- prefix and the -ide ending.
Where people slip
Unlike ionic naming, subscripts here are stated through prefixes rather than inferred from fixed ion charges.
