Answer:
B) Ni(s)
Step-by-step explanation:
The question inquires which of the substances listed in the options is composed of the metallic bond. This means that we have to carefully consider the options and identify which of them is a metal. Clearly, only Ni(s) is a metal.
Metallic bonds result from the electrostatic attraction between metal cations and delocalized electrons. The nature of metallic bonding accounts for many of the physical properties of metals, such as conductivity and malleability(Khan Academy).
