Phosphorus Properties - What are the Physical Properties of Phosphorus?
What are the Physical Properties of Phosphorus? The Physical properties of Phosphorus are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Phosphorus are as follows:
What are the Physical Properties of Phosphorus?
- White phosphorous is white, waxy solid. It gives off a greenish-white glow. It glows in the dark, is spontaneously flammable when exposed to air and is deadly poison It does not dissolve well in water
- Red phosphorous is a powder which can vary in colour from orange to purple, due to slight variations in its chemical structure. It does not dissolve in many liquids
- Black phosphorous, is made under high pressure, looks like graphite powder and has the ability to conduct electricity
Phosphorus Properties - What are the Chemical Properties of Phosphorus?
What are the Chemical Properties of Phosphorus? They are the characteristics that determine how it will react with other substances or change from one substance to another. The better we know the nature of the substance the better we are able to understand it. Chemical properties are only observable during a chemical reaction. Reactions to substances may be brought about by changes brought about by burning, rusting, heating, exploding, tarnishing etc. The Chemical Properties of Phosphorus are as follows:
What are the Chemical Properties of Phosphorus?
- White phosphorus exhibits the most activity
- Red and black phosphorus are considerably more passive in chemical reactions
- The oxidation of white phosphorus occurs through a chain reaction. The oxidation of phosphorus is often accompanied by chemiluminescence
- Chemiluminescence is the emission of light during a chemical reaction that does not produce significant quantities of heat
- Phosphorus combines directly with all halogens
- When heated with metals, phosphorus forms phosphides.
