Detailed explanation-1: -An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating an ionic bond.

Detailed explanation-2: -Ionic bonding results in compounds known as ionic, or electrovalent, compounds, which are best exemplified by the compounds formed between nonmetals and the alkali and alkaline-earth metals.

Detailed explanation-3: -A negative ion or anion is an atom that has gained electrons. An atom that has lost negatively charged electrons becomes positive. A positive ion or cation is an atom that has lost electrons. Nonmetals tend to gain electrons and become anions.

Detailed explanation-4: -Ions and ionic bonds. Some atoms become more stable by gaining or losing an entire electron (or several electrons). When they do so, atoms form ions, or charged particles. Electron gain or loss can give an atom a filled outermost electron shell and make it energetically more stable.

Detailed explanation-5: -Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation).
