Which shell of electrons is the primary determinant of the electrical behavior of a material?

What is the important of electrical properties for non ferrous metal?
Electrical properties of non-ferrous material 1. It provides low resistance to the circuit. 2.conductivity of electrons(current) is better. 3.
How many valance electrons does a semiconductor have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
What type of material allows electrons to move freely?
Electrons move freely in a solid, as in a metal
What are materials that allow electrons to move through them easily?
A conductor. Most metals are conductors-they enable electrons to move freely through them, carrying an electrical charge. Most non-metals (notably excluding graphite, an isotope of carbon) are insulators which means that they do not allow an electrical charge to be carried through them.
Why do materials with extra electrons often stick to a material with missing electrons?
The electrostatic force attracts the opposite charges.
Electrons do not readily flow through what material?
The material that electrons do not readily flow through in the electrical trade is classed an an insulator.
A material used for electrical wiring must have what?
free electrons
A material used for electrical wiring must have?
free electrons
Do electrons have the same magnetic behavior as particles of iron?
Electrons are the reason any material is magnetic or not. including iron.
How does an electrical insulator work?
Any material that does not allow the free flow of electrons.
What do you call a material that doesn't allow electrons to move through it?
an Electrical-Temphobe
How does a material acquire a positive electrical charge?
By losing electrons.
What is the difference between a electrical conductor and a electrical nonconductor?
Simply put an conductor is a material that lets free electrons flow through it. When free electrons are flowing that is called current. So an electrical conductor will have current pass through. Non-conductive material will not allow these electrons to flow and no electricity can be passed through. Good conductors have almost no resistance to electron flow.
What is a electrical conduction?
An electrical conductor is a material whose molecules contain loose valence electrons that can easily be passed between molecules. When an electrical potential difference (aka voltage) is applied to the surface, the electrons drift toward or away from it (depending on the charge) - this is referred to as the conduction of electricity.
What condition necessary for a material to be term as good conductor?
It must have large number of free electrons for electrical conduction.
What is a good insulator of electicity?
It is usually a material that has no free electrons in its out valance rings. This condition makes it hard for free electrons to move from one atom to another atom easily. Without this movement of electrons the material is classed as an insulator. Easy movement of electrons from one atom to another is classed as a conductor the very opposite of an insulator. In the electrical field, the purpose of any insulating material is to separate electrical conductors without passing current through it. Material like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon, and rubber are very good electrical insulators. Insulating material is used as a protective coating on electrical wire and cables. For article on electrical insulating material click on the related link.
Is glass insulator or conductor?
Glass is an insulator, as it DOES NOT conduct current. It is a material which has no free electrons available to flow as electrical current. Conductors, like copper or aluminum, have free electrons, or electrons in the outer shells of their atoms that are easily knocked loose. These electrons flow from negative to positive when an electrical potential (voltage) is applied across the material. We call the flow of electrons "current".
