There are 5 valence electrons in the atom phosphorus.
Valence electrons are the outermost electrons in an atom, and they determine the atom's chemical properties. Atoms with a full valence shell of electrons tend to be stable because they have a lower energy state. Atoms will gain, lose, or share electrons to achieve a full valence shell, which increases their stability.

it was to gain 3 more valence electrons so it can be like the noble gases.
4 valence electrons dude!
3 valence electrons
That neutral silicon atom has four electrons in its valence shell.
The valance electrons. The outer level of electrons every atom has. Every atom has a full valance shell at 8, so only the Nobel gasses are nonreactive naturally and other atoms either donate or accept the number of electrons needed to come to an octet of electrons.
