Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors. The two oppositely charged ions attract one another, and the ionicbond is the electrostatic force of attraction between them.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. So they make a strong ionicbond in between them to form nucleosome. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In the case of aluminium iodide an ionicbond with much covalent character is present. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. To form an ionicbond, either a valence or bonding electron separates from one atom and becomes attached to another atom to form oppositely charged ions. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thus, the rare gas halide molecules are formed by an ionicbond since the excited electron of the noble gas is partly transferred to the halogen atom. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Hard acids are acids with relatively ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In general, compounds with ionic bonds have high normal boiling points, if they do not decompose before reaching such high temperatures. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. To allow the movement, all ionic bonds along the plane have to be broken. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Most insulators (or dielectric materials) are held together by ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Atoms and complexes connected by non-covalent bonds such as hydrogen bonds or ionic bonds are generally not considered single molecules. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Ionic bonds may be seen as extreme examples of polarization in covalent bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Alkaline earth difluorides possess strong ionic bonds but are insoluble save for beryllium difluoride, which also exhibits some covalent character and has a quartz-like structure. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Also, ionic bonds are not the strongest bonds, and halides can not normally scratch glass plates. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The ions interfere with the weak ionic bonds of proteins. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Because these dipole forces are weaker than covalent or ionic bonds, molecular solids are soft and have relatively low melting temperature. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For example, a crystal of sodium chloride (common salt) is made up of ionic sodium and chlorine, which are held together by ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. They form stable products with hard bases, which are bases with ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Oxygen in ionic bonds with silicon forms a tetrahedral coordination which in turn forms sheets of silica. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. They are intermetallic compounds, containing partially metallic and partially ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A solid compound containing metals can also be an insulator if the valence electrons of the metal atoms are used to form ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. They can be covalent bonds or ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is due to the way that metals bond chemically: metallic bonds (as opposed to covalent or ionic bonds) have free-moving electrons that transfer thermal energy rapidly through the metal. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. As noted above, covalent and ionic bonds form a continuum between shared and transferred electrons; covalent and weak bonds form a continuum between shared and unshared electrons. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For example, in a crystal of sodium chloride (common salt), the crystal is made up of ionic sodium and chlorine, and held together with ionic bonds. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. With other atoms, fluorine forms either polar covalent bonds or ionic bonds.
