The answer is Index fossils its the only answer it could be
Density as you should know is equal to mass/volume. Solve for the volume.
Now, you know that you are dealing with a sphere. You know the volume of a sphere is V= 4/3pi r ^3.
You know the volume so just solve for r
Answer:francium
The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
