Look at the number of bonding domains. for example, Calcium has a charge of +2 and oxygen has a charge of -2. They bond, and calcium gives up 2 electrons to the same oxygen, creating a double bond, forming a binary compound (Calcium Oxide) It all depends on the elements. The main thing is the number of electrons being transfered.
The Covalent Bond. Atoms can combine to achieve an octet of valence electrons by sharing electrons. Two fluorine atoms, for example, can form a stable F 2 molecule in which each atom has an octet of valence electrons by sharing a pair of electrons.A pair of oxygen atoms can form an O 2 molecule in which each atom has a total of eight valence electrons by sharing two pairs of electrons.The term covalent bond is used to describe the bonds in compounds that result from the sharing of one or more pairs of electrons.hen a sodium atom combines with a chlorine atom to form an ionic bond, each atom still contributes one electron to form a pair of electrons, but this pair of electrons is not shared by the two atoms. The electrons spend most of their time on the chlorine atom.
