(inorganic chemistry) Any of a series of oxides of a particular metal that has the fewest atoms of oxygen per molecule.
Oxygen frequently combines in various proportions with a substance, rendering it an oxide, but without advancing it to the state of an acid. In order to distinguish each compound thus formed, the language of chemistry is very systematic. The first is called a protoxide; the second a deutoxide; and the third, a paroxide.
Use protoxide when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
