Identification of unknown elements

  This was a pretty cool lab that we did. I really liked it! In class we have been working with moles, and the weight of different elements in grams. In this lab we had several different unknown elements and we weighed the element and divided that number in grams by the number that was given to us in the chart with the letters on it. We then got that number and looked at all of the elements on the periodic table and figured what it was closest to and figured out what the element was. It was a little confusing at first, but after we did it, it was pretty easy to figure out!

Here is a link if the chart with all of the unknown elements. If you click identification of elements on the bottom you can look back and forth and see what all of the elements are.

No, not this kind of mole! 

A mole is a unit of measurement. It is a quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. This number of particles is Avogadro's number, which everyone knows as 6.02x10^23. Referring to a large number of things is pretty much why the  mole was invented!
