Chemical bonds, ionic, covalent and metallic GapFill

There are three main types of strong chemical bonding:

•  transition bondingionic bondingpolymeric bondingatomic bonding, which occurs between a metal and a non-metal
•  covalent bondingpolymeric bondingnon-metallic 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  massentropyelectronsneutrons to the non-metal, and positive and negative  atomscompoundsmoleculesions are formed, with  fullunchargedoverfilledcharged outer shells. A compound is formed with  a giantan irregulara polymerica long structure. Ions are attracted to other ions with the opposite  structurereactivitychargemass in all directions.

In the second bonding type, electrons are  delocalisedrepelledsharedreplaced between atoms. Many of these compounds are  nanostructuressmall moleculesionicweakly bonded but can also be polymers or giant covalent structures, such as  sodium chloridesilveroxygendiamond.
