When an atom gains or loses electrons, an ion is formed. It explains ionic … An ionic bond is a bond in which an atom donates one or more electrons to another atom to produce ions (cations and anions). An ionic bond is a type of chemical bond in which positively charged cations and negatively charged anions are held together by electrostatic attraction. Since they form strong ionic bonds they have higher melting and boiling points. Because most metals form cations and most nonmetals form anions, formulas typically list the metal first and then the nonmetal. When an atom loses an electron, it In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions (cations) and negatively charged ions (anions), [1] which results in a compound with no net electric charge (electrically neutral). For covalent bonds, the bond dissociation energy is associated with the interaction of just two atoms. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. 3. In an ionic compound, the number of cations and anions are equal. For example, iron(II) has a 2+ charge; iron(III) a 3+ charge. Ionic compounds are electrically neutral because the charges of the cations and anions that make up the compound cancel each other out.

Atoms interact with each other through the formation of chemical bonds. When an atom gains or loses electrons, an ion is formed. Therefore, when metallic and nonmetallic atoms combine, they usually form ions and ionic bonds. Cations and Anions Ionic bonds involve a cation and an anion. The atom that gains electrons becomes a negatively charged ion, known as an anion. When an atom loses an electron, it becomes a cation. Noble gas atoms are very stable, so when the nonmetallic atoms form anions, they gain enough electrons to get the same number of electrons as the nearest larger noble gas atom. 4. In covalent compounds, electrons are shared between bonded atoms and are simultaneously attracted to more than one nucleus. When naming ionic compounds the term ion is dropped and the cation and anion names are placed together, with the cation always listed first and the anion listed last.
