Carbon has four valence electrons. this means that it either needs to gain four electrons or lose four electrons in order to have a full octet in its outer shell. what type of bond is carbon most likely to form with another carbon atom?

a)a covalent bond, because carbon ions are unstable
b)an ionic bond, because carbon ions are unstable
c)an ionic bond, because carbon will form a stable positive ion
d)a covalent bond, because carbon will form a stable negative ion
