The family of "nobel gases" or the last row on the right. (Neon, Argon, and so on)
These electrons are called "outershell electrons" or "valence electrons."
A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
Molecules or covalent compounds are formed by the sharing of valence electrons.
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
Because they are the only ones involved in bonding. For example, when an forming an ionic compound one atom loses its valence electrons and one gains electrons to make its valence electron shell complete.
Valence electrons are the electrons in the outermost shell. They are the electrons available for bonding and generally determine the number of bonds an atom can make
the number of valence electrons determine the reactivity of the atoms

A full set of valence electrons typically consists of 8 electrons, except for hydrogen and helium, which have a full valence shell with 2 electrons.
alkaline earth metals or group 2 elements have two valence electrons and make +2 ion.
Molecules or covalent compounds are formed by the sharing of valence electrons.
Valence electrons form the bonds between atoms in a molecule.

You would need 1 more electron to make a Chlorine atom stable with 7 valence electrons. This additional electron would allow Chlorine to achieve a full valence shell of 8 electrons, following the octet rule.
There are 15 electrons in phosphorus, 45 electrons from five fluorine atoms, and they make 60 electrons altogether.
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
