The type of bond that are show in the diagram above is option C which is metallic bond and it is a chemical bond or electrostatic force of attractions that exist between conducted electrons in metal ions.
<h3>What is metallic bond?</h3>
Metallic bond is a form of chemical bond or force of electrostatic attractions that exist between the positively charged metal ions which give room for conduction of electricity or heat.
This type of bond only occur in metallic substances or objects alone. This is characterized by high boiling and melting points.
Therefore, The type of bond that are show in the diagram above is option C which is metallic bond and it is a chemical bond or electrostatic force of attractions that exist between conducted electrons in metal ions.
