  • Not sure if this will help but I took it from my old chemistry book.

    Argon can be produced from liquid air by fractional distillation. It can also be produced by heating nitrogen gas from the atmosphere with hot magnesium or calcium. The magnesium or calcium combines with nitrogen to form a nitride:

    A little argon always occurs as an impurity with nitrogen. It remains behind because it does not react with magnesium or calcium.

    Argon also occurs in wells with natural gas. When the natural gas is purified, some argon can be recovered as a by-product.

  • Is that how the question is worded? Did she read the material? I think that it may have something to do with decay...

  • The answer will be in the text book somewhere. Assignments are funny that way.

  • Argon doesn't normally combine with another chemical, Argon is a noble gas. Is there more to the question?
