Symbol, Group Phosphorus combines with allthehalogens forming phosphorus halides which are all covalent compounds. Covalent bonds, which hold the atoms within an individual molecule together, are formed by the sharing of electrons in the outer atomic orbitals. The carbon-12 molecule, which is still used as a normal today, comprises six protons and six neutrons for the atomic mass of twelve amu. As we know, the p shell can hold a maximum of six electrons there is a scarcity of three electrons. Phosphorus is a colorless, red or silver-white chemical element and belongs to the group of nonmetals. To locate Phosphorus on periodic PBr3 Lewis Structure, Molecular Geometry, Hybridization and Polarity. Phosphorus is used in the manufacture of safety matches (red phosphorus), pyrotechnics and inflammatory shells.
