Where do they write "phosphorous"? They don't indiscriminately sprinkle 'u' after every 'o'. That would be "phosphourous".

(https://en.wikipedia.org/wiki/Red_Phosphorous#Spelling_and_etymology https://en.wikipedia.org/wiki/Red_Phosphorous#Spelling_and_e...) > According to the Oxford English Dictionary, the correct spelling of the element is phosphorus. The word phosphorous is the adjectival form of the P3+ valence: so, just as sulfur forms sulfurous and sulfuric compounds, phosphorus forms phosphorous compounds (e.g., phosphorous acid) and P5+ valence phosphoric compounds (e.g., phosphoric acids and phosphates).
