Carbon has the atomic number of 6, meaning each carbon atom has a total of six electrons. Two are in the completed inner orbit, while four electrons are found in the atom’s outermost orbit. This basically means that carbon has four valence electrons (outer electrons that are available for forming bonds with other atoms). Because of this arrangement within the atom’s orbits, carbon is called tetravalent.
