Answer 1

c)vibrating and in a regular arrangement

Step-by-step explanation:

Copper is a chemical element represented by the symbol Cu and having atomic number 29. Copper is a transition metal which means its subshells are not completely filled and that is why they are vibrating in the room temperature. But copper is a solid at room temperature with regular arrangement of atoms.

Hence, the correct answer is "c)vibrating and in a regular arrangement".
