Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
How does insulator get charge by rubbing easier than conductor?
When insulators are rubbed, charges are transferred through a process called triboelectric charging. Insulators have high electron affinities, making it easier for them to gain or lose electrons during rubbing. Conduction, on the other hand, requires mobile electrons which are more restricted in insulators compared to conductors.
How some material are better conductors of electricity than others?
Materials that are better conductors of electricity typically have more free electrons that are able to move easily through the material when a voltage is applied. Metals are good conductors because they have many free electrons in their outer energy levels. In comparison, insulators have few free electrons and do not conduct electricity well.
Why do conductors have a lower specific heat than insulators?
Conductors have lower specific heat compared to insulators because conductors have more free electrons that are available to transfer heat energy quickly through the material. Insulators have fewer free electrons and therefore heat is transferred more slowly through the material, resulting in a higher specific heat capacity.
Is a block of wood a conductor?
No, wood is an insulator rather than a conductor. Conductors allow electricity to flow through them easily, while insulators restrict the flow of electricity. Wood's high resistance to the flow of electrons makes it unsuitable for conducting electricity.
Do conductors generally have more electrons than protons?
It would be more correct to say that conductors have more free charge carriers (electrons or "holes") than insulators. For example, in the metallic model, positive nuclei in a fixed position are surrounded by a sea of electrons not necessarily tied to any particular nucleus, and thus free to flow when electromotive force is applied. In an insulator, those same electrons are more resistant to electromotive force and tend to remain in the same position until a much higher ("breakdown voltage") force is applied. The number of electrons themselves is less relevant, any given conductor may have more or less electrons than an insulator.
Do Conductors conduct heat more slowly than insulators?
No, a conductor (of heat) will conduct heat more efficiently than an insulator.
Why is current established more easily in a semiconductor than in an insulator?
Semi conductors will pass electricity through with some restriction. Insulator will not pass electricity
Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
What material conductors electric current better than an insulator but not as well a conductor?
semiconductor
Explain why metals are good conductors?
Metals have between 1 and 3 valence electrons, and they therefore find it easier to give up electrons, to form a complete outer shell, than to acquire more electrons, since they would need between 7 and 5 additional electrons to form a complete outer shell of 8. When you have a collection of atoms which all are predisposed to give up electrons, the result is called a metallic bond, which consists of a cloud of shared electrons. Because these electrons are not bound to any specific atom, they move easily and conduct electricity well.
How does insulator get charge by rubbing easier than conductor?
When insulators are rubbed, charges are transferred through a process called triboelectric charging. Insulators have high electron affinities, making it easier for them to gain or lose electrons during rubbing.

Metals are good conductors because they have many free electrons in their outer energy levels. In comparison, insulators have few free electrons and do not conduct electricity well.
What is the difference between the resistance of conductor and insulator?
Conductors allow most, if not all, electricity to pass through it. This is due to "wandering electrons" that aren't tightly bound to the nucleus of the conductor itself.Resistors conduct some, but not all electricity to pass. It somewhat resists it, hence resistors.Insulators do not allow electricity to pass through it due to the electrons being so tightly bound to the nucleus.
Why do conductors have a lower specific heat than insulators?
Conductors have lower specific heat compared to insulators because conductors have more free electrons that are available to transfer heat energy quickly through the material. Insulators have fewer free electrons and therefore heat is transferred more slowly through the material, resulting in a higher specific heat capacity.
How many valence electrons do conductors such as copper have?
good conductors have only one or two electrons in the outer shell while insulators have many more, around eight
Why are metals better conductors than ceramics?
Metals have a higher density of free electrons which can move easily, allowing for efficient conduction of heat and electricity. In contrast, ceramics have a more fixed atomic structure with fewer free electrons, limiting their ability to conduct heat and electricity effectively.
