Electrons in conductors, like copper wire, are free to roam throughout the metal in the presence of the ions that have released
Scrat [10]

Answer:

  • <u><em>No, I would not consider a metal to be a plasma because plasma is just another state of matter, and the copper wire is in solid state.</em></u>

Explanation:

Metal is not a state of matter. Metals can be solid or liquid (molten) depending on their melting point and the temperature at which they are.

Plasma is a state of matter, similar to gas, but it is reached only at very high temperatures like in the Sun. The particles in plasma state are not neutral atoms or molecules but negatively charged  ions and electrons.

The copper wire is yet a solid, thus it cannot be considered a plasma.

Metals can be in plasma state only if the temperature is too high, like the temperatures in the stars. In fact, the metals in the Sun and other hotter stars are in plasma state.

A certain type of material allows electricity to flow through it, but it does not flow quickly or easily through it. Is the mate
Deffense [45]
A substance through which an electrical current flows poorly would be said to be a poor conductor. That is, the substance has a low conductance (or conductivity). There’s a nuance between the two terms, but it shouldn’t matter for our purposes.

Since such a material resists the flow of electric charge, the material can be said to have a high resistance (or high resistivity).

Mathematically, resistance and conductance are reciprocals of one another; a low conductance implies a high resistance, and a high conductance implies a low resistance.
