phosphorous
Emitting soft luminescence
Phosphorous is the adjective form relating to phosphorus, specifically describing compounds where phosphorus has a lower oxidation state than in phosphoric compounds: phosphorous acid.
The spelling distinction matters in chemistry—phosphorous describes the element's properties or certain compounds, while phosphorus is the element itself.
