Definition von ionic bond im Englisch Englisch wörterbuch
A type of chemical bond where two atoms or molecules are connected to each other by electrostatic attraction
A chemical bond between two ions with opposite charges, characteristic of salts. Also called electrovalent bond. Electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when one or more electrons are transferred from one neutral atom (typically a metal, which becomes a cation) to another (typically a nonmetallic element or group, which becomes an anion). The two types of ion are held together by electrostatic forces in a solid that does not comprise neutral molecules as such; rather, each ion has neighbours of the opposite charge in an ordered overall crystalline structure. When, for example, crystals of common salt (sodium chloride, NaCl) are dissolved in water, they dissociate (see dissociation) into two kinds of ions in equal numbers, sodium cations (Na^+) and chloride anions (Cl^-). See also bonding; covalent bond
a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains to electron to form a negative ion
