Chemical Bond

Definition - What does Chemical Bond mean?

Chemical bonds are the bonds between atoms that are formed during chemical reactions. These bonds allow substances containing two or more atoms to be formed. They are formed by electrostatic forces of attraction between the oppositely charged nuclei and electrons, or by a dipole attraction.

Safeopedia explains Chemical Bond

Chemical bonds occur in the world all around us. Even the most basic things from oxygen to table salt require chemical bonds to form. There are many different types of chemical bonds, including covalent bonds, ionic bonds, metallic bonds and hydrogen bonds. Atoms form bonds in order to attain a stable electronic configuration. Oxygen (O2) is an example of a covalent bond, where atoms share their electrons. In contrast, table salt or sodium chloride (NaCl) is an example of an ionic bond, where an electron from an atom is transferred to another causing the two atoms to be positively and negatively charged, thus attracting each other.
