Ionic Bonding - YouTubeIn this video, Paul Andersen explains how ionic solids form when cations and anions are attracted. All ionic bonds have some covalent character, but the larger the difference in electronegativity between the two atoms, the greater the ionic character of the interaction. However, in covalent bonds, the electrons are shared between the two atoms. Both types result in the stable electronic states associated with the noble gases. Table salt, NaCl, is a good example of this type of compound. The ability to conduct electricity in solution is why these substances are called electrolytes. Most of these solids are soluble in H 2O and conduct electricity when dissolved. The resulting Na + and F - ions are electrically attracted to each other.Īt the macroscopic scale, ionic compounds form lattices, are crystalline solids under normal conditions, and have high melting points. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.įormation of NaFAn electron is transferred from Na to F. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Ionic bonds involve a cation and an anion. An ionic bond is based on attractive electrostatic forces between two ions of opposite charge. Enhancing the Cycling Stability by Tuning the Chemical Bonding between Phosphorus and Carbon Nanotubes for Potassium-Ion Battery Anodes ACS Appl Mater Interfaces. This exchange results in a more stable, noble gas electronic configuration for both atoms involved. Ionic bonding is a type of chemical bond in which valence electrons are lost from one atom and gained by another. electrolyteAn ionic compound which dissolves in H2O, making the resulting solution capable of conducting electricity.electronegativityThe tendency of an atom to attract electrons to itself.Ionic solids form crystalline lattices, or repeating patterns of atoms, with high melting points, and are typically soluble in water.They both achieve a more stable electronic configuration through this exchange. A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron.Ionic bonds are formed between cations and anions.
