Valence electrons.
valence electrons
each dot in an electron-dot diagram represents valence electrons or "available" electrons of each element. For example, Oxygen has 6 valence electrons so it has six dots around it. The number of valence electrons are found at the top of each group on the periodic table. Nitrogen has 5, Oxygen 6, Fluorine has 7...and so on! hope this helps
The outermost electrons are called VALENCE electrons.
Cl-
It represents the number of valence electrons in the atom.

On the outermost (or valence) electron shell.
Electrons farthest from nucleus are valence electrons. They are present in outermost orbit.
Valence electrons are the outer layer of electrons, the part that reacts. Argon is a noble gas, so it has a full valence electron level. It has eight valence electrons.
Fluorine has 7 valence electrons. 2 In the first electron shell, and 5 in the second electron shell.
valence electrons are bound to atoms and are used to bind atoms into molecules. free electron are free, either they are in the conduction band "electron gas" of a metal or they are in a vacuum (perhaps in a vacuum tube).
