Detailed explanation-1: -Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.
Detailed explanation-2: -Formation of ionic bond 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.
Detailed explanation-3: -Ionic bonding involves gaining / losing electrons forming compounds between metals and nonmetals.
Detailed explanation-4: -Ions are formed when an atom gains or loses electrons from the outermost energy shell. Elements form cations when an electron or electrons are lost to achieve a full duplet or octet. If the element gains an electron or more than one electron, it is called an anion.
