Morphology
This is a straightforward noun–noun chemical compound: combining 'barium' (the element) with 'protoxide' (an oxide with minimal oxygen) yields 'the protoxide of barium' (an oxide of barium). Although technical, the meaning is compositionally predictable from the constituents and follows common chemical naming patterns found across languages, so a learner who knows both words can infer the MWE's meaning.
Etymology
Barium protoxide gets its name from two parts: barium, from a Greek word meaning 'heavy' because its minerals feel heavy, and protoxide, an old name meaning the 'first' or simplest compound with 'oxygen'. So the name means a heavy metal joined with oxygen, which is why it refers to an oxide of barium.
