Describe the range of the radii of most atoms

The radii of most atoms are actually measured in the Ǻ, or Angstrom. We can do it in nanometers too, however. 
First, we take the radius of the smallest atom, He (Helium). Atomic radius = .031 nm. The largest atom, stable atom is Fr (Francium), with atomic radius = .27 nm. 
Therefore, the typical atomic radius is between .031 and .27 nm.

If it releases 5 tons a day and there are 7 days a take that answer and multiply by 5 percent (0.05) to find the amount released in one week. leave a comment if you need more .
