The chemical compounds, for instance, are phosphorous this or that.

(If you speak a romance language, it jumps out at you because the adjective has an extra syllable - e.g. 'fosforo' vs. 'fosforoso'.)

That's true of phosphorous acid (where the name distinguishes it from phosphoric acid), but otherwise English chemical names use the noun form of the positive ion (e.g. phosphorus pentoxide).
