(Sb), and last but not least bismuth(Bi). All of the members in the Nitrogen family have 5 electrons in their valence shell. It’s Atomic number is 15 with its Atomic mass at 31, It consist of 15 Protons, 15 Electrons and 3 energy shells. It has 23 known Isotopes and the only stable Isotopes is 31P which is considered a monoisotopic element.
Phosphorus is a solid in lab temperature and a nonmetal. The melting point of phosphorus is 44.1° C, and the boiling point of phosphorus is 280.5°C. The freezing point of Phosphorus is anything below the melting point and it can not sublimate. Phosphorus is a mineral (Phosphate rock) it is one of the most recurring pnictogen in earth's crust but it is not found free in nature, it is mostly found in minerals mostly phosphates. The price of phosphorus is around 30$ per 100g.
Phosphorus is highly reactive element that catches fire. Phosphorus likes to bond with other elements such as nitrogen, oxygen and sulfur. White phosphorus is so reactive with oxygen that when they make contact the element catches fire instantly. Phosphorus is always found as a oxide, most of its compounds are used for fertilizer. All of the element in the nitrogen family are highly reactive.
Phosphorus has many uses for us in our day to day life. White phosphorus is used to make flares and incendiary devices. Red phosphorus is the red material on the the tip of matches that you use to start fires. The biggest use of phosphorus is for things such as fertilizer to help grow plants and crops. A interesting fact about phosphorus is that phosphorus is what helps build strong bones and teeth.
