It is simpler to understand and predict how atoms will interact to form chemical bonds when you know how phosphorus (atomic number 15) is configured: 1s2 2s2 2p6 3s2 3p3.
The periodic table, also known as a table of elements, reveals that the atomic number of phosphorus, denoted by the symbol P, is 15. As a result, an atom has 15 protons. The ion's mass number is 15 + 16 = 31. The ion has a net charge of 3 due to its composition of 15 protons and 18 electrons, which is three more electrons than protons.
The phosphide ion, P3-, is the most stable monoatomic ion produced from phosphorus. Phosphorous already has 5 valence electrons, so adding 3 more will make it isoelectronic with the stable noble gas argon, resulting in the formation of the P3- ion.
