What are the two main types of chemical bonds that are found in compounds?
Ionic and covalent
Ionic bonds are formed between two compounds when one of the atoms donates electron(s) to the other. The bond is not directional. There can be more number of electron donating atoms and/or more number of electron accepting atoms. Both the atoms complete their octet by donating and receiving electrons simultaneously.
Covalent bond is formed when atoms share their electrons to mutually complete their own octets. The shared pair of electrons belong to both the atoms contributing. This bond is highly directional, that is, it is along the direction of the shared pair(s) of electrons.
Example- organic compounds like methane, benzene etc.
