Document Summary
Chemical bond is the electrical attraction that holds atoms or ions together in a molecular element or in an ionic or molecular compound. When bonds form, the atoms or ions that are joined function as a unit. Molecular elements are molecules that consist of atoms of the same element, such as nitrogen gas, n2(g). Molecular compounds comprise atoms of 2 or more different elements. Finally, an ionic compound is a pure substance composed of 2 or more ions combined in a fixed ratio. Ionic bond is the electrostatic attraction between oppositely charged ions. Ionic compound is a composed of positively and negatively charged ions in a fixed ratio, held together by electrostatic attraction. This electrostatic attraction creates a crystal lattice of sodium chloride, nacl. The ions in a crystal lattice are arranged so that attractions between opposite charges are maximized and repulsions between like charges are minimized.
