Meaning of protoxide | Babel Free
Definitions
Any of a series of oxides of a particular metal that has the fewest atoms of oxygen per molecule
Examples
“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.”
