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.
No.
Copper is a very good conductor and is commonly used for wires because it has a very low resistance, which means the electricity will flow freely through it.
Nichrome has a very high resistance, so electricity flowing through it will slow down and lose energy, making it a bad conductor.

Nichrome conducts alot of current, so more heat can be generated.
Because it is EASY to use FAST to install gives up heat faster then steel or cast Iron and just about anyone above the age of 4 can solder it and it is light to handle
Copper is a very Good conductor, the current would simply follow through the copper without dissipating much energy (which means nothing would light up).
Because Nichrome has a high resistance and copper has a low resisitance.
because nichrome has lower temp.coeff of restivity
A nichrome wire has high resistance and gets heated faster, saving electricity.
yes it does -------------------- You might say they are polar-opposites. Copper is specifically used where low resistance is desired. NiChrome is often used as a resistance wire. For example, model rocket engines utilize nichrome wire to ignite the fuel because the resistant wire will glow red-hot when electric power is applied.
nichrome alloy is made by mixing up of the metals nickel and chromium.
Even though gold and copper are in the same family, copper is much more reactive than gold. This is why Copper rusts more than gold, and why there are so many copper compounds (IE copper silicate...). Copper is higher in the family, giving it these characteristics.
Yes, brass is cheaper than copper.

It might be newer than copper or less tested because this metal has been mixed with other metals such as iron

if it is heated above 1200 degrees celsius than it melts
When hydrogen gas passed over heated cupric oxide, the hydrogen is oxidized and displaces copper from the copper oxide as metallic copper, because hydrogen is higher than copper in the electromotive series. Water vapor is also produced by the reaction.
The Pauling electronegativity of hydrogen is higher than the electronegativities of aluminium or copper.And copper is more reactive than aluminium.The red poweder obtained is copper as a metal.
Solid copper appears to gain mass when heated in air, because the copper reacts with oxygen in the air to form copper oxide. However, the actual mass of the copper does not increase; the mass of the solid increases by a value equal to the mass of oxygen removed from the air.
It gives green color . Copper is more reactive than silver therefore it displaces silver from silver nitrate and forms silver + copper nitrate
Copper ore, usually in the form of malachite, needs to be refined through a chemical reaction, rather than a mechanical separation as with washing. It needs to be ground and heated to separate out the copper metal from the compound.
nichrome alloy is made by mixing up of the metals nickel and chromium.
Copper is a better conductor of electricity than gold.
Here are more than two- Galena, Gold, Copper, Sulfur, Pyrite.
