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.
start. 2.8 Covalent bonds join atoms into molecules through electron sharing The second kind of strong chemical bond is the covalent bond, in which two atoms share one or more pairs of outer-shell electrons. Two or more atoms held together by covalent bonds form a molecule. For example, a covalent bond connects two hydrogen atoms in a molecule of the gas H2. Table 2.8 shows four ways to represent this molecule. The symbol H2, called the molecular formula, tells you that the molecule consists of two atoms of hydrogen.
