A conductor differs from an insulator in that a conductor is an?
A conductor is a material that has one or a few electrons in the outer shell of its atoms. These electrons are easily knocked loose, or are already moving about in the material. When a voltage is applied to a conductor, these electrons are repelled by the negative polarity and attracted by the positive polarity. Their movement is called "current". a conductor is a material that transports electrons and electricity can pass through it, metals are good conductors. a insulator is something that is a barrier to electrons and can not pass electricity, rubber is a good insulator.
Is the looseness of outer electrons in metal atoms the reason metal is both good heat conductors and electrical conductors?
They carry energy from one part of the conductor to another.
Do good conductor causes fire?
Yes, good conductors can cause fires. This is because they have valence electrons which will help move the fire to the other sources.
How does conductors allow heat to go through?
Heat energy can be transfered through a conductor or medium, in three ways. Radiation, which is how the sun transfers energy, through waves. Convection, which is how wind works, the transfer of heat by mixing particles together. Conduction, which is how your hand warms up when someone touches it. The particles transfer their heat energy to adjacent particles.
Why are some metals better conductors than others?
The number of free electrons in a given volume is different for each metal; many electrons is good conductivity.
Can electrons flow in conductors?
Yes, electrons can flow through conductors. Conductors are materials that allow the free flow of electric charge, such as electrons, due to their loosely bound electrons. This movement of electrons is what allows the flow of electric current in a conductor.
Why are conductors electrons able to move throughout a conductor?
Because they are bound loosely
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
How are conductors and insulators different give an example of a conductor and an insulator?
conductors, such as metals, have free electrons, meaning their electrons are not strongly bonded to the atoms and a charge can move easily throughout the whole object, an insulator such as wood does not have free electrons so a charge is likely to stick in one area of the insulator.
How is conductor different from an insulator?
A conductor allows the flow of electricity due to the presence of free-flowing electrons, while an insulator restricts the flow of electricity because it lacks free electrons to carry current. Conductors have low resistance, while insulators have high resistance to the flow of electrons.
Is gold a good conductor for electrons?
Yes indeed it is one of the best conductors of heat and electricity
How many valence electrons does conductors such as copper have?
only one valance electron does a conductor such as copper have.
What the role of loose electrons in heat conductors?
They carry energy from one part of the conductor to another.
What allows a conductor to conduct electricity?
Conductors are substances where electrons can freely move from atom to atom.
Why are good electrical conductors?
Their electrons move freely. This is due to the bonding. In metallic bonding the nuclei are surrounded by a sea of electrons rather than discreet paired electrons with covalent bonds.Metals are good conductors of both electric charges and heat because their electrons are "loose."(info from physics book) Some good metal electrical conductors are copper which has a high conductivity, the best pure metal conductor is silver, aluminum is another good conductor. Some good metal electrical conductors are copper which has a high conductivity, the best pure metal conductor is silver, aluminum is another good conductor.
Why can conductors conduct electricity?
Conductors, like metals, have many free electrons that are able to move easily through the material. When an electric field is applied, these free electrons can flow, allowing the conductor to conduct electricity.
What materials do electrons easily move through?
Electrons easily move through conductive materials such as metals like copper and aluminum. These materials have loosely bound electrons in their outer energy levels, allowing for easy transfer of charge.
