Chemical bonds, ionic, covalent and metallic GapFill

There are three main types of strong chemical bonding:

•  transition bondingionic bondingatomic bondingpolymeric bonding, which occurs between a metal and a non-metal
•  covalent bondingnon-metallic bondingpolymeric bondingtransition bonding, which occurs between non-metals
•  transition bondingpolymeric bondingmetallic bondingperiodic bonding, which occurs between metals

In the first type of bonding, the metal gives up  neutronsentropyelectronsmass to the non-metal, and positive and negative  compoundsionsatomsmolecules are formed, with  unchargedfullchargedoverfilled outer shells. A compound is formed with  a polymerica giantan irregulara long structure. Ions are attracted to other ions with the opposite  reactivitymasschargestructure in all directions.

In the second bonding type, electrons are  replaceddelocalisedsharedrepelled between atoms. Many of these compounds are  ionicsmall moleculesnanostructuresweakly bonded but can also be polymers or giant covalent structures, such as  sodium chlorideoxygensilverdiamond.
