The primary element in a copper wire is copper itself, which can range from 99.9% to 99.999% pure. Copper wires are often also alloyed with other elements such as tin or silver to improve their properties like strength and conductivity. Insulation materials like PVC or nylon are also used around the copper wire to protect and insulate it.
Heating copper wire in the presence of air at high temperatures causes a chemical change because it leads to the oxidation of copper. When exposed to oxygen, copper reacts to form copper oxide, resulting in a new substance with different properties. This transformation involves a rearrangement of atoms and bonds, characteristic of a chemical change, as opposed to a physical change where the substance remains the same.
I believe intrinsic impedance is more tied to the medium, thus is defined in terms of magnetic and electric permeability and electrical conductivity, while characteristic impedance is a "wider" look at the impedance. For example, you can calculate the intrinsic impedance of a 18 awg copper wire, or air, or a vacuum. If you wanted to use coax cable with an 18 awg core, you would be looking at the characteristic impedance, not the intrinsic impedance of the copper that will be carrying the waveform.
Fundamentally, "copper" is a noun, the name for a particular chemical element. It is often used as a "substantive adjective" when paired with another noun, as in "copper wire", "copper jewelry", or "copper coins".
Resistance will only be reduced by changing the thickness of the wire or the wire's temperature. It's apparent impedance can be changed by placing it in an electric field as well.

how much copper is in copper wire
No. Copper wire is a solid
No.. Copper wire isn't
No, copper wire is not magnetic.
No, copper wire would not produce a distinctive color in a flame test. The flame test is typically used for metals that produce easily identifiable colors when burned in a flame, such as lithium (red), sodium (yellow), or potassium (purple). Copper does not exhibit this characteristic.
