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. The atom gaining one or more electron becomes an anion-a negatively charged ion.
Detailed explanation-2: -An ionic bond results from the transfer of an electron from a metal atom to a non-metal atom.
Detailed explanation-3: -Covalent bonds are the most important means of bonding in organic chemistry. The formation of a covalent bond is the result of atoms sharing some electrons.
Detailed explanation-4: -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.
