What crystals conduct electricity because valence electrons are free to move throughout the crystal lattice?
p type semiconductors. These semiconductors have small concentrations of dopant atoms which have insufficient bonding electrons, so there are "holes" in the bonding arrangements. As electrons jump into these places the holes move in the opposite direction because the jumping electrons leave these spaces behind. So the spaces move around inside this sea of overwhelming bonding electrons. It is called hole conduction, or p-type conductivity. For example silicon doped with gallium.

Why do metals conduct current easily?
Metals conduct current easily because of their free-flowing electrons. In metals, electrons are not bound to individual atoms but instead move freely throughout the material, allowing for the easy flow of electrical charge. This mobility of electrons makes metals efficient conductors of electricity.
Can tetrachloromethane conduct electricity?
No because it forms covalent bonds and electrons are not free to move in covalent bonds. Therefore, electricity (the flow of electrons) cannot happen. - Ch
Why do conducturs conduct electricity?
conductors conduct electricity well because the electrons are easily transfered from atom to atom.
Which is a good conductor of electricity lead or sulfur why?
Lead is a good conductor of electricity compared to sulfur. This is because lead has free-flowing electrons that can easily carry an electric current, while sulfur lacks these free electrons and does not conduct electricity as well.
Metals conduct both heat and electricity because?
metals have free electrons that can move easily through the material, carrying heat energy and electrical charge. This ability to transfer energy and charge makes metals good conductors of both heat and electricity.
Why do solid crystals of ionic compounds conduct electricity when the crystals dissolve in water?
Solid crystals of ionic compounds do not conduct electricity because the ions are not free to move. When the crystals dissolve in water, the ionic bonds are broken and the ions become free to move, allowing them to carry electric current.
Why do metals conduct heat and electricity?
Electrons in metals are mobile and carry (conduct) electricity and heat energy. Plato: Free moving electrons carry both heat and electric current throughout the system
Why do metals giant covalent structures not conduct electricity?
Metals have a sea of delocalized electrons that can move freely throughout the structure, allowing them to conduct electricity. In contrast, giant covalent structures like diamond and silicon have electrons localized in strong covalent bonds, making them insulators and unable to conduct electricity.
Why is electricity observed because of the presence or movement of electrons?
Electricity is observed due to the presence or movement of electrons because electrons carry a negative charge and when they flow through a conductor, they create an electric current. This flow of electrons is what we perceive as electricity.
Are copper sulphate crystals good conductors of electricity?
Yes, copper sulfate crystals can conduct electricity when dissolved in water because the ions present in the solution are free to carry the electric current. However, solid copper sulfate crystals do not conduct electricity as well because the ions are not free to move.
Why do metals conduct current easily?
Metals conduct current easily because of their free-flowing electrons. In metals, electrons are not bound to individual atoms but instead move freely throughout the material, allowing for the easy flow of electrical charge. This mobility of electrons makes metals efficient conductors of electricity.
Why is iron a good conductor of electricity?
Iron is a good conductor of electricity because it has a high number of free electrons that are able to move freely throughout its atomic structure. This allows electricity to flow easily through iron, making it an efficient conductor.
Why a conductor will not produce static electricity?
A conductor will not produce static electricity because electrons in the conductor are free to move around easily. This means any excess charge will be quickly redistributed throughout the conductor, preventing the buildup of static electricity.
Why is silver able to conduct electricity?
Silver is able to conduct electricity because it has a high number of free electrons that are able to move easily throughout the metal when a voltage is applied. This movement of electrons forms an electric current that can flow through the silver, allowing it to conduct electricity efficiently.
Why conductors conduct electricity?
Conductors conduct electricity because they have free electrons.
Why and how do metallic compounds conduct electricity?
Metallic compounds conduct electricity because they have delocalized electrons that are free to move throughout the structure. When a voltage is applied, these electrons can flow easily and carry the electric current. This is due to the metallic bonding in which metal atoms share their electrons in a "sea of electrons."
What does the resistance of the flow of electrons cause?
it cause no electricity because of the resistance but.... if your question was..... "the caused by the flow of electrons" then the answer well be ( it cause electricity )
