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.
Since four electrons are shared between two atoms in a double bond, more energy is required to break the bonded atoms apart compared to a single bond. Breaking a double bond between oxygen atoms requires three times the energy necessary to break a single bond between oxygen atoms. The same is true for nitrogen. What makes a double bond stronger also makes it shorter. The average bond length for a carbon double bonded to another carbon is 13% shorter than that of two single bonded carbons.
