Electrons are subatomic particles that orbit around the nucleus of an atom. They carry a negative charge and are responsible for chemical reactions and the formation of chemical bonds. The number of electrons in an atom can be determined by its atomic number, which represents the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is equal to the number of protons.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
See link below and to left for a good image of Bohr's model.
It represents the number of valence electrons in the atom.
Two pairs of shared electrons represents a double covalent bond.
Atomic numbers are the number of protons and electrons in a atom.

The electrons in the outermost shell of an atom is known as the valence electrons. These valence electrons determine the reactivity of the atom.
