That depends on what nickel you are talking about. Is it a US coin, a Canadian coin, what year is it? Compositions change both from country to country and from year to year. Try being more specific in your question, in order to get a proper answer.
Unfortunately nickel is usually alloyed into a metal; for example stainless steel has high chromium and nickel content in order to boost its corrosion resistance. When you scrap your nickel alloy, you should get payed accordingly to how much nickel is in the alloy.
The coin is made from a alloy of silver, copper and manganese
Copper itself is one of the elements. It contains nothing but copper. It might be alloyed with nickel sometimes, but that would not always be the case.You may be thinking of the fact that nickel was sometimes found mixed in with copper ore. Its hardness compared to that of copper caused such problems for miners in Saxony that they called it "Kupfernickel", a German word that translates roughly as "Devil's copper". Eventually the "Kupfer" prefix was dropped, giving us the word we use today.
Karen should look for the flask labeled with the chemical formula "NiO," which represents nickel(II) oxide. The "Ni" stands for nickel, and the "O" stands for oxygen, with the "II" indicating that nickel has a +2 oxidation state in this compound. If she does not see the label, she may need to ask her teacher for assistance.
It depends on whether it's made of standard copper-nickel alloy, or is one of the part-silver "war nickels" minted when nickel metal was needed for the war effort. Please see the Related Question for details.
The last year of minting for the 'Indian Head' nickel (some times called the 'Buffalo' nickel) was 1938.
No, 1866 was the first year for a US nickel.
The amount of 'nickel' in a nickel has not changed, it's still .250.
no
It is an alloy of Copper and Nickel metal. It is mostly copper surrounded by a thin layer of Nickel to keep the silver color that we are accoustumed to.
It depends on whether you want to or not. It's not rare or scarce and still found in circulation. Most are only face value.
1866 was the first year for a Nickel, please look at the coin again
a penny is the original so thats what you should buy because its way funner to ride and you cud keep it in your locker
You should keep utility bills for at least one year before shredding them.
The millimeter should be sufficient. If you want greater precision, measure with micrometers. A nickel made in the USA is about 2 millimeters thick, which is equivalent to 2,000 micrometers. However, keep in mind that the precise thickness will vary from nickel to nickel, depending on the amount of wear.
You should keep utility bills for at least one year in case you need them for tax or billing disputes.
