When ion bond is a metal with a non-metal combined. Achieve the noble metals by recording configuration, non-metals by release of electrons. The binding partner can simply replace an electron in order to minimize their energy. Thus the metal remains positive (Cation), the non-metal negatively charged (anion). The resulting ions move now at each other and are bound together. Through this commitment can be many more atoms together. They assign the ions then become a regular grid.
Sodium chloride (NaCl), the salt is a simple example of this Bindungstyp.
