Will a copper coin conduct electricity?
Each copper atom has lost one electron and become a positive ion. ... The electrons can move freely through the metal. For this reason, they are known as free electrons. They are also known as conduction electrons, because they help copper to be a good conductor of heat and electricity. Therefore, copper is an outstanding material to use for conducting electricity! Hope it helped :)
Why the metal copper is used in plugs?
Copper is used because it is a good conductor. The pins are generally made of brass, an alloy of copper, as it is harder. Fuse clips are often made of copper. Also: Copper is desirable in electric circuits because it's the second-best conducting metal. The reason we don't use the first-best is on account of cost. The first-best is silver.
Why does the nichrome wire get heated first than copper wire?
Because Copper is an excellent conductor of electricity it would take too much copper wire to make an element having sufficient resistance to fit into the small space provided in any normally-sized electric heater. For that reason heating elements must be made from metals which have a much higher electrical resistance than Copper. Special alloys of metals such as Iron, Cobalt, Nickel, Zinc and Manganese have been invented for this purpose.
Why are the three pin plugs are made of brass and not copper or steel?
Brass is used for the manufacture of plug pins for the following reasons. It is a good electrical conductor and is cheaper than other materials such as copper. It is a hard alloy material, therefore it is very wear resistant and will not wear or mark easily. Furthermore, Brass is corosion resistant and will not tarnish easily. Brass is also stiff and therefore will not bend easily when inserted in to the socket.
What elements are used in an electric heater filament?
The heating element in electric heaters and irons is made from an alloy of nickel and chronium called nichrome. It is usually made in the form of wire. The wire is often wound around a flat sheet of mica for support. Mica is a thin layered mineral that can withstand high temperatures.
Is a glass pane a conductor?
No. Glass is used as the OPPOSITE of a conductor- it is an insulator. This is the reason telephone poles used to use glass objects that looked similar to bells to tie the telephone wires to the poles. For a better conductor of energy, look to metals. Aluminum and copper are excellent conductors, as is gold.
Why gold and copper are good conductors of an electrical current?
Yo, These 3 are the best First = Silver (Ag) Second= Copper (Cu) Third = Gold (Au)
Why are electrical wires made up of copper?
Most electrical wires are made up of copper instead of any other metal. The reason for this is that copper is such an excellent conductor of electricity and it is relatively inexpensive.
Is gold a good conduct of gold?
It does conduct fairly well, but it's not among the very best conductors. One reason that connectors are sometimes plated with gold is that while gold isn't as good a conductor as, say, copper or silver, unlike those metals gold doesn't tarnish, and gold is a much better conductor than copper or silver oxide.
Why is a cooking pot made out of copper cooks faster?
Copper is a conductor, which means it conducts heat more quickly, hence heating up faster. The same reason is for why copper is used in electricity cabling.
Why do buildings being wired use copper wire?
Copper is an excellent conductor that is reasonably inexpensive, it is also malleable and its oxide is a conductor. Aluminum has also been used as it has most of the properties of copper, except that its oxide is an insulator which causes the resistance of connections to rise over time and presents a fire hazard. Some countries (e.g. the United States) ban the use of aluminum electrical wiring for this reason. Silver is a much better conductor than copper, but its much too expensive to use. Those are the main choices for building electrical wiring, everything else is either not a very good conductor or is much much too expensive.
State 2 reasons for stating that copper is a metal and sulphur is a non metal?
2 reason why copper is metal and Sulphur is a non metal is that copper is a good conductor of heat while sulphur is and also solid is the state of copper and not that of sulphur.
Is the element nickel in an US nickel?
A standard US nickel coin contains 1.25 grams of the element nickel. The rest is copper. However from mid-1942 to the end of 1945, the U.S. minted 5-cent coins out of an alloy of silver, copper, and manganese because nickel metal was needed for the war effort. Their silver content is the reason "war nickels" are worth more than other nickels of a similar age.
Nickel and copper lie next to each other on the periodic table how do their structures differ?
Nickel is 3d8 4s2, while copper is 3d10 4s1. If I remember this copper exception to filling its d shell in order correctly the reason is balance in pairs of electrons as the d shell is filled across the row. Chromium is also an exception in this row. ( do not quote me on this, but ask a chemist )
Silver is a better electrical conductor than copper but is rarely used for electrical purpose give 1 reason for this?
The cost is the sole reason not to use silver. Its value outweighs its usefulness in this capacity. That is not quite true Besides its monetary value it has a tendency to tarnish which eventually defeat the conductivity purposes

Why has phytomining been used to produce gold nickel and copper but is only rarely used to produce zinc and lead?
this question came up in the AQA chemistry text book and in some exam style questions. so the answer is: Phytomining is used to produce gold nickel and copper because they are found in low grade ores the main reason is that gold, nickel and copper are below carbon in the reactivity series which means they are found in native state. (sometimes copper can be found in low grade ores) but phytomining is used rarely to produce zinc and lead is because they are more reactive than gold nickel and copper. this is why phytomining been used to produce gold nickel and copper but is only rarely used to produce zinc and lead.
