Question

An ionic bond is formed due to?
Sharing/transfer

Answer 1

The bonds formed between two ions with opposite charge are called ionic bonds. These bonds are held together with the help of electrostatic force. Ionic bonds are the strongest type of bonds.

Complete answer:
An atom donates or receives energy in order to complete its octet or be in a stable condition.Ionic bond is formed between two atoms when one atom completely transfers its ion to another resulting in a chemical bonding. Ionic bonds are only formed when one atom loses its ion while another gains an ion. Ionic bonds are also called electrovalent bonds. Ionic bonds are only formed between metals and nonmetals. Since losing and gaining of ions create opposite charges on the atoms both atoms get stable. They attain their nearest inert gas configuration. The potential energy is less in these bonds due to electrostatic attraction. Since the transfer of ions takes place the positive ion formed is called cation whereas the negative ion is called anion. Only atoms with large differences in electronegativity are able to form ionic bonds.

Note:
Ionic bonds have a high melting and boiling point. Ionic bonds are most reactive since they have charge separation. Due to the presence of ions, ionic bonds are good conductors of electricity in molten states.
