Valence electrons actually are the outer-shell electrons so as you can imagine the valence electrons are on the outside; the most outside particle in an atom.
Valence electrons are the outermost electrons in an atom. They are located in the outer energy levels or orbitals, specifically in the highest principal energy level. These valence electrons are involved in chemical bonding and determining the atom's reactivity.
There can be up to 18 valence electrons in a atom, these atoms are krypton, xenon, radon, and sometimes mentioned is ununoctium but is an "unknown element" so the element is not always mentioned
As metals have to become metal ions in order to chemically combined with nonmetals they have to lose their valance electrons. This process is associated with making the atoms smaller.
A carbon atom has only four electrons in its valance energy shell. This allows for four other bonding possibilities. Carbon is also an atom that has covalent bonding properties which means it shares its electrons with the molecules that it is bonded to.

This electron is a valance electron.
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.

is a compound
A fluorine atom has 7 valance electrons. This can be identified by looking which group fluorine is located, which is group 7. However when the atoms get bigger this rule does not apply so easily.
8 valance electrons in valance shell means that atom is stable.
Ionic type of bonding is highly favored among the ionic species, where one atom has tendency to donate electrons and the other has tendency to accept electrons in order to attain a stable atomic coniguration with a filled outer shell of electrons.
