Phosphorus can exist in several allotropes, each with different properties. The most common forms are white phosphorus, which is soft and waxy, and red phosphorus, which is more stable and has a harder, more brittle texture. Black phosphorus, another allotrope, has a layered structure and is considered the least reactive and most stable form. Overall, phosphorus can be classified as either hard or soft depending on its allotrope.
