Phosphorus has five valence electrons.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.

The electron configuration of phosphorus is [Ne]3s2.3p3.
A phosphorus atom has one nonbonding pair of electrons.
Phosphorus has 5 valence electron. It forms anion by gaining 3 electrons.
Phosphorus has five valence electrons.
Phosphorus has an electron configuration of 1s2 2s2 2p6 3s2 3p3. Another way to write that is [Ne] 3s2 3p3. The [Ne] represents the fact that the beginning of phosphorus' electron configuration is the same as Neon's.
The valence electrons are the outermost (highest energy) s and p sublevels. There are 5 valence electrons in a phosphorus atom, and it is in period 3, so its valence electron configuration is 3s23p3.

Phosphorus, like all atoms, tries to achieve a full electron shell. For Phosphorus to achieve its full shell and obtain an electron configuration that is isoelectronic with Argon, it must gain 3 electrons. Therefore, Phosphorus forms a -3 anion.
Phosphorus in is 3rd period. So it has 3 electron shells.
The electron configuration of phosphorus is [Ne]3s2.3p3.
The noble gas electron configuration of Phosphorus is [Ne] 3s2 3p3
