- Confusing it with 'peroxide' (which has more oxygen).
FAQ
Frequently Asked Questions
No, it is a highly specialised term used almost exclusively in chemistry and materials science.
No, it is strictly a term for chemical compounds.
A suboxide has less oxygen than the standard oxide, while a peroxide contains the O₂²⁻ ion or an O-O group and typically has more oxygen relative to the metal.
Technically, yes. Carbon monoxide is considered the suboxide of carbon, as it contains less oxygen than carbon dioxide (CO₂).
A chemical oxide containing a relatively small proportion of oxygen, typically less than the normal oxide of the same element.
Suboxide is usually technical/scientific in register.
