How small is an atom?
If we took all the empty space out of all six billion people on the planet, then all six billion of us could fit inside ______________________. Take an educated guess and then check out the website below to see if you were even close.
It is very difficult to imagine an atom's size and structure because it is so small. I came across a very interesting website so please check it out.

How close are scientists to seeing an atom? Check out this website, http://www.lbl.gov/Science-Articles/Archive/MSD-NCEM-TEAM05.html to determine the answer. What kind of microscope are they using to see atoms?
