Answer: The correct answer is ionic bond.
Step-by-step explanation:
Ionic bond is defined as the bond which is formed from the complete transfer of electrons from one atom to another atom. The atom which donates electron is known as electropositive atom and it forms positive ion and the atom which accepts the electron is known as electronegative atom and it forms negative ion.
The ionic bond is formed between the electrical attraction of two oppositely charged species.
Example: The bond formed between sodium and chlorine atoms to form sodium chloride compound which is NaCl.
Hence, the correct answer is ionic bond.
