Phosphorus (P) has an atomic mass of 15. Find out about its chemical and physical properties, states, energy, electrons, oxidation and more.
Phosphorus is a nonmetal, solid at room temperature, and a poor conductor of heat and electricity. Phosphorus occurs in at least 10 allotropic forms, the most common (and reactive) of which is so-called white (or yellow) phosphorus, which looks like a waxy solid or plastic.
Table \(\PageIndex{2}\) lists the ion names and ion formulas of the most common polyatomic ions. For example, \(\ce{NO3^{−}}\) is the nitrate ion; it has one nitrogen atom and three oxygen atoms and an overall 1− charge.

Phosphorus is the 15th element in the periodic table and has a symbol of P and atomic number of 15. It has an atomic weight of 30.97376 and a mass number of 31. Phosphorus has fifteen protons and sixteen neutrons in its nucleus, and fifteen electrons in three shells.
21 Νοε 2020 · Neutron Number and Mass Number of Phosphorus. Mass numbers of typical isotopes of Phosphorus are 31. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.
Phosphorus (pronunciation: FOS-fer-es) is a highly-reactive element classified as a non-metal represented by the chemical symbol P [1, 2, 3]. It mainly exists in its two allotropic forms, including the waxy, white solid and the non-crystalline, solid red that is obtained by heating white phosphorus [3, 4, 5]. Phosphorus Symbol. Isotopes.
