ionic bond

Definition
- Noun:
- A type of chemical bond: An ionic bond is a chemical bond formed through the electrostatic attraction between oppositely charged ions. It is created when one atom transfers one or more electrons completely to another atom.
- Electron transfer bond: This bond results from the complete transfer of valence electron(s) from a metal atom (which becomes a positively charged cation) to a non-metal atom (which becomes a negatively charged anion).
Usage Examples
- Noun:
- Table salt, or sodium chloride, is held together by a strong ionic bond.
- The ionic bond between calcium and chlorine forms the compound calcium chloride.
- In an ionic bond, the resulting ions are held together by strong electrostatic forces.
Advanced Usage
- "Form an ionic bond": Describes the process of ionic bond creation.
- Sodium and fluorine atoms form an ionic bond to create sodium fluoride.
- "Ionic bond strength": Refers to the energy required to break the bond.
- The ionic bond strength in magnesium oxide is very high due to the charges on the ions.
Variants and Related Words
- Ionic compound (n): A chemical compound composed of ions held together by ionic bonds.
- Sodium chloride is a classic example of an ionic compound.
- Electrovalent bond (n): A synonym for ionic bond, emphasizing the electrical nature of the bond.
- An electrovalent bond is another term for an ionic bond.
Synonyms
- Electrovalent bond: A direct synonym highlighting the bond's formation via electron transfer and resulting electrical charges.
- Polar bond (Note: This is a less precise synonym, as "polar" often describes covalent bonds with uneven electron sharing, not complete transfer. Ionic bonds are the extreme case of polarity.)
Related Phrases and Concepts
- Ionic bonding (n): The general process or phenomenon of forming ionic bonds.
- Ionic bonding is common between metals and nonmetals.
- Lattice energy (n): The energy released when one mole of an ionic solid is formed from its gaseous ions; a measure of ionic bond strength.
- The high lattice energy indicates very strong ionic bonds in the crystal.
Noun
- a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion
