No. they are too massive. For a given electrical charge, protons are about 1800 times more difficult to move then an electron is.
But real quantities of matter may be transferred in an electrical arc. Which may be unwanted in electrical switches, but is desirable in arc welding.
Hardly. If you are thinking about electrical currents, the charge carriers are mainly lighter particles, such as electrons or holes. In liquids, the charge carriers may also be ions.
The protons are bound inside the nucleus and are not free. In conductors, the electrons are free to move.
Free electrons move toward positive charges
Nonmetals in the solid state tend to be brittle and poor conductors of heat.
In a solid conductor there will be only one conductor ,but in stranded conductors there are several conductors twisted together to make a whole conductor ,this is mainly done to increase flexibility of the Conductor .
In the solid state generally no. In solution or molten when the ions ra efree to move in an electric field, they can be reasonable conductors
most metals are good heat conductors, because their electrons are free to move around the protons in like a 'sea of electrons' and that enables them to be good charge carriers. (:
Stranded conductors are more flexible than solid conductors.
electrons
The reason they are in solid and molten states is because of there electricity conducting capability's
By bundle conductors, I am assuming that you mean stranded conductors. If you actually mean bundles of wires, then the bundles could be either stranded or solid and your question does not make sense. Stranded conductors have two main advantages over solid conductors. The first is flexibility. Stranded conductors are much more flexible than their solid counterparts. The second main advantage is skin surface area. Alternating current tends to travel towards the outer skin of a conductor. This is known as the skin affect. Stranded wire has a lot more skin surface area than solid wire does. There may be more advantages, but these are the two I could think of off the top of my head.
Conductors.
Covalent compounds are generally not good conductors because the electrons are not free to move. Solid ionic compounds are generally not good conductors because the ions are not free to move as they are locked in place in a lattice (this is not true when ionic compounds are molten or in solution!)As always there are a few exceptions, graphite is covalent but the electrons are delocalised and it does conduct, there are also a few other inorganic conductors.There are also some conductive organic polymers which have delocalised free electrons, these are called ICP's .There is also a small group of what are called fast ion conductors where the crystal structure allows the ions to wander, some are used in solid oxide fuel cells.
