Detailed explanation-1: -Ionic bonds are formed between two or more atoms by the transfer of one or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations.
Detailed explanation-2: -There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.
Detailed explanation-3: -Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
Detailed explanation-4: -The covalent bond is formed when two atoms are able to share electrons whereas the ionic bond is formed when the “sharing” is so unequal that an electron from atom A is completely lost to atom B, resulting in a pair of ions. Each atom consists of protons, neutrons and electrons.
