Question

What molecular level property allows copper to be an ideal material to be used in electrical wiring? A) The solubility of copper and copper compounds. B) The freedom of electrons in the metallic bonding. C) Attractive forces within the copper alloyed wire. D) A high degree of crystallinity in the bulk structure.

Answer 1

B. the freedom of electrons in the metallic bonding

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

Copper is known as the best conductor of heat and electricity. This is because in copper there is availability of free electrons.

And, as it is known that electricity is the flow of electrons. This means that since copper metal contains a number of free electrons. Hence, it can easily conduct electricity.

Electronic configuration of copper is
`[Ar]4s1 3d^(10)`

Thus, we can conclude that freedom of electrons in the metallic bonding at molecular level property allows copper to be an ideal material to be used in electrical wiring.
