Physical and Chemical Properties
Phosphorus comes in three different colors, white phosphorus, red phosphorus, and black phosphorus. White phosphorus is very flammable, and will spontaneously catch fire when it reacts with air. It is also a fatal poison. Red phosphorus's color can vary from orange to purple, due to changes in it's chemical structure. Black phosphorus is a good conductor of electricity, and when under pressure, can be formed to look like graphite.
Of the four states of matter, phosphorus is normally a solid, but you can melt it into a liquid by get it's temperature to be 44.2°C. This is phosphorus's melting point. You can also boil phosphorus into a gas by getting it to a temperature of 277°C. This is it's boiling point.
Phosphorus can sometimes be found in a powdery form. It has an atomic mass of 30.97 atomic mass units, and a density of 1.82 grams per cubic centimeter.
Phosphorus is a multivalent element, which means that it had more than three valence electrons. In fact, phosphorus has 5 valence electrons. These valence electrons rest on phosphorus's third and final energy level. There are three different ions of phosphorus, +5, +3, and -3. This means that the number of electrons
