Answer: The chemical bond is known as ionic bond.
Explanation:
Ionic bond is defined as the bond which is formed by the complete transfer of electrons from one atom to another atom.
The atom which looses electrons is known as electropositive atom and the atom which gains electrons is known as electronegative atom.
For example: The bonding between NaCl is ionic bonding which is formed by the transfer of electrons from sodium to chlorine atoms.
Covalent bond is formed by the sharing of electrons between the two atoms forming a bond. For Example: The bonding between HCl is covalent bonding which is formed by the sharing of electrons between hydrogen and oxygen atoms.
Hence, the chemical bond is known as ionic bond.
