Your first step should be to analyse the compound. For example, if the compound is carbon, you know it always has a valence of four, so, if it has a formula C2H4 (ethylene) it obviously has a double bond. There are difficulties here because benzene C6H6 can be considered to have 6 1.5 C-C bonds, being aromatic.
In an ionic chemical bond, electrons from the metallic substance are transferred to the atoms of the nonmetallic substance. Covalent bonds occur between nonmetallic substances. An example would be the bond formed between two hydrogen atoms and one oxygen atom to form the compound water (H 2 O). In a covalent bond, the electrons are shared between the atoms. The third major type of chemical bond, the metallic bond, is formed between metallic atoms.
