One example of a material that doesn't carry electrons is an insulator, such as rubber or glass. Insulators have a high resistance to the flow of electrical current, preventing the movement of electrons through them.
No. The "n" and "p" does not refer to the negative or positive charge, but to the fact that there are atoms that can easily "donate" electrons (n-type), or atoms that can easily "accept" electrons (p-type).
A material through which electrons do not easily travel is called an insulator. Insulators have high resistance to the flow of electric current due to the lack of free electrons available to carry the charge. Examples of insulators include rubber, glass, and plastic.
Metals conduct electricity because they have free-moving electrons that can carry electric current through the material.
The electrical conductivity of a material generally increases with temperature. This is because at higher temperatures, the atoms in the material vibrate more vigorously, allowing more free electrons to move and carry electric current.
The conductivity of a material generally increases with temperature. This is because higher temperatures cause the atoms in the material to vibrate more vigorously, allowing electrons to move more freely and carry electrical charge more effectively.
Materials carry current because of the way the electrons of the material behave. Current is proportional to the number of electrons. If the electrons are loosely bound on the material then they are available to carry current along the material. Copper is a common metal who's configuration means that the electrons are loosely bound and as such is very good at carrying current. If on the other hand the electrons are tightly packed into the atoms in the material then they aren't available to carry current. Materials such as glass and plastic are good examples.

For a material to conduct electricity, it must have free movable electric charges, such as free electrons or free ions, in order to 'carry' electricity. In the case of metals, there is a 'sea' of delocalized electrons. These free electrons can 'carry' the electricity, and thus, it is a conductor.

Wherever there is material, there are protons. But protons are not the things that carry the charge around in electrical circuits. Electrons do that.
Metals are conductive because they have free-moving electrons that can carry electric current easily through the material.

The purpose of a wire is to carry some sort of electrical signal. This requires that the electrons in the material be able to move freely. Materials with free movable electrons are called "metals".
insulator. Insulators have high resistance to the flow of electric current, which hinders the movement of electrons through the material. This property makes insulators useful for applications where electrical conductivity needs to be limited.
It means that it's a material whose outer shell electrons move freely across the surface of the material. Conductors can carry an electric current
Gold, silver, copper, aluminium, iron, and lead are all quite good. Most metals carry electrons easily. A material that does that is called a good "conductor".
