Explanation:
Detailed explanation-1: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion.
Detailed explanation-2: -Ionic bonding Definition: An ionic bond is formed when valence electrons are transferred from one atom to the other to complete the outer electron shell.
Detailed explanation-3: -In ionic bonding, atoms transfer electrons to each other. Ionic bonds require at least one electron donor and one electron acceptor. In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.
