What allow valence electrons in metals to move throughout the metal?
Wiki User
∙ 11y ago
metal atoms being so close to one another that their outermost level overlap. Cause of the overlapping metallic bonds extend throughout the metal in all direction, so valence electrons can move throughout the metal.

Are valence electrons tightly bound in insulators?
Yes!! That is why they do not allow any form of energy to penetrate into the insulator.
Is aluminum a conductivity?
Yes due to the fact it is a metal and metals have delocalised (free) electrons which allow the electrons to move around the metal conducting heat and electricity easier than non metals
How do you explain why metals are good conductors?
Metals are good conductors because they consist of a lattice of atoms with free electrons. The free electrons allow a current to flow through. When a negative charge is applied at one end, the electrons are repelled from the negative charge, and move towards the other end.
Why are metals such great conductors of electricity?
Metals are in metallic bonds with delocalized electrons that are free moving, making metals conductors of electricity. Atoms of metals can move and vibrate due to the above and can conduct heat very well.
How does the structure of metal allow it to carry an electricle current?
the same way as it conducts heat. Through free electrons. the structure of an atom works like this. there is a nucleus in the middle with shells around the outside. the most inner shell can hold two electrons whilst all the others hold eight. if, like copper, an atom has its most outer shell with only one shell away from another full shell. then it will have a maximum number of free electrons. and so the more free electrons (max. of seven) the better the conductor of everything. thank you.
How many valence electrons does insulator 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.
Why are the valence electrons found in metallic bonds different from other bonds because of what?
their valence electrons are free-roaming they allow for the conductivity of electricity APEX :) <3 JAmie
True or false does a conductor allow electric current o flow through easily?
Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.
All metals are conductors?
by defining all metals would be wrong as synthetic metals would change the properties of the metal. in terms of natural metals or alloys, yes they are all conductors as their arrangements allow them to have delocalised electrons to carry electricity

How Does the metallic bond allow metals to conduct electricity?
Freely moving electrons.
Are valence electrons tightly bound in insulators?
Yes!! That is why they do not allow any form of energy to penetrate into the insulator.
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.
Is aluminum a conductivity?
Yes due to the fact it is a metal and metals have delocalised (free) electrons which allow the electrons to move around the metal conducting heat and electricity easier than non metals
Why do metal conduct?
As metals are good conductors, they allow the electrons to pass through them. Hence they conduct electricity.
Metals are good conductors because?
Because of the VALENCE CLOUDS! Look this up. The atoms bond by these and share electrons. As electricity flows in a cable, what is actually happening is the negatively charged electrons are moving along one at a time from atom to atom. Larger currents mean the electrons move faster. Electricity flows from negative to positive! Metals have good conductivity because of the freedom the electrons have to move around. This also explains magnetic properties in metals (a similar effect) and the greater the freedom the better the conductor. Plastics; elasto-mers, poly-mers and mono-mers bond in a manner that does not allow this movement of electrons and as such do not conduct electricity.
How are valence electrons special?
The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react. With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. Valence electrons are the only electrons that are available to be shared/transferred in a bond.
