Which element has a crystalline lattice through which electrons flow freely?
calcium
Why is zinc negative amd copper positive?
Zinc is more electronegative than copper. As a result, zinc acts as the anion(anode), while copper loses electrons and becomes positive (cathode). Electrons flow from the zinc to the copper ( - to +)
Why is solid sodium an excellent conductor of electricity but solid sodium chloride is an insulator?
An atom's conducting and insulating properties relate to its electron configuration. Sodium metal is a conductor because electrons can flow freely through the metal. On the other hands, electrons are not free to flow in sodium chloride, and thus its an insulator.
What is the definition for electrical energy?
Energy made available by the flow of electric charge through a conductor.energy resulting from the flow of charged particles, such as electrons or ions:)energy resulting from the flow of charged particles, such as electrons or ions
Why does copper conduct electricity so well?
== == Electricity is the flow of electrons. Electrons move from one atom to the next adjacent atom. Electrons exist within shells at different distances from the nucleus of the atom. Copper has only one electron in it's outermost shell and therefore it is easy to strip the electron away and move it to the next atom, which simultaneously sheds it's electron. In addition, copper is very dense, meaning that the atoms are very compact...or close together to allow this transfer more freely.
What do you call a material that electrons will flow through freely?
conductor
Which element has a crystalline lattice through which electrons flow freely?
calcium
What is a material through which electrons do not easily flow?
insulator
Which type of material that allows electricity to flow but not as freely?
Note that "electricity" doesn't flow, only current does, which is one aspect of electricity, does. Current is the flow of electrons. Good conductors are metals, such as copper or aluminum. Materials that allow the flow of electrons, but not as freely as good conductors are known as semiconductors. These are primarily silicon or germanium, that is "doped" with specific types of impurities to allow their current to be better controlled by the application of a voltage. Heat will also increase the flow of electrons in a semiconductor.
Copper is a good conductor of electricity because its electrons are what?
The copper (the positive protons) hold the inner negative electrons securely, but the outer most negative electrons of the copper atom are easily disloged and become free electrons, apply a potential difference (volts) between terminals of say a car battery, and the terminals are joined by copper wire then electrons will flow from one terminal to the other - the electron flow is from negative to positive terminal.Hope this helps I have just answered the question simply!
What materials allow electricity to flow freely?
Because of freely moving of electrons in the material
How is a electric current produced?
When some metals form, their electrons are not stolen nor shared, but pooled. The electrons freely float between the atoms. This is called a metallic bond, or pooling. The electrons flow freely between the atoms, and when two wires are put on either side of the metal, it channels the electrons to flow through to the other wire.
Which part flows freely aroud the nucleus?
Electrons flow around the nucleus
Why are most metals called good conductors?
Because such metals allow electricity to flow more freely through them than it can flow through most other things (wood, for example, is a poor conductor).
Why isn't water used in a voltaic cell?
Because electrons can't flow between water molecules. When ions such as copper II chloride are dissociated in solution, electrons are able to flow freely between Cu and Cl ions in the cell via the salt bridge
How electricity travels through wires?
copper in wires is a metal, and like all metals it is made up of atoms bound together. Basically, atoms are made of a nucleus in the middle, and electrons revolving around the nucleas. In all elements except metals, the nucleus doesn't "let go" of the electrons (unless there is a chemical reaction, but dont worry about that for now), but in metals, the electrons are"allowed to go around" to other nucleuses, electrons are allowed to flow around atoms freely in a metal. It is this flow of electrons that is electricity. however a driving force is needed to make the electrons flow around the copper wire, this comes from a battery or a dynamo.
