Answer:
B. They bond identical atoms together
Step-by-step explanation:
Metallic Bond: This is the bond that exists among the atoms of the metal. This is a type of electrostatic attraction between conduction electrons of metallic atom and their positively charged metal ions.
(figure attached)
Example:
Copper is a metallic element and its atoms consist of metallic bond among their selves.
Options A, B, D are not correct as all states for a kind of ionic bond formation.
Ionic bond:
It form by the complete transfer of electron from one atom to other
It is formed among two atoms of different electronegativities.
Also metals are electro-positive and non -metals are electro-negative so they form ionic bond.
Example is NaCl where sodium is a metal and Chloride is non-metal and they from ionic bond.
