Phosphorus is solid at room temperature. That said, phosphorus is an element that can take different solid forms, depending upon how it was prepared and other factors. These different forms are called "allotropes".
So a room temperature sample of phosphorus could be the common red phosphorus, used to make matches and road flares; the poisonous waxy white phosphorus, which is used to make incendiary bombs; or the rare purple/black phosphorus. You can see pictures of all three allotropes by googling "phosphorus".
