What is ionic bonding?
September 24, 2013 6:15PM
An ionic bond is when an electron leaves one atom and
exothermically enters into orbit around another. These to
oppositely charged ions now attract eachother. Ionic bonds are
generally formed between metals and nonmetals.
Ionic bonds result from the mutual attraction between oppositely charged ions. They tend to be stronger than covalent bonds due to the coulombic attraction between ions of opposite charges. To maximize the attraction between those ions, ionic compounds form crystal lattices of alternating cations and anions. Ionic compounds are usually formed only between atoms whose difference in electronegativity is large. Bonds form at particular distances even though the attraction between oppositely charged ions increases strongly with decreasing distance. The opposing strong internuclear repulsion maintains the separation between ions. Bond strength, it will be shown, depends mostly on the charges present on each ion and the distance between them. Small, highly charged ions will form strong bonds while large, minimally charged ions will form weaker bonds.
