So start out here, we have one, or in this case, we'll call it 100% at zero time, and that's here as well.

When answering the question Assuming the polonium nucleus was initially at rest, Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure.

So we're gonna go from here down about 1/4 of the material left down there, and then we'll go down to about an eighth of the material left for the third half life because it's 1/2 of the remaining. So at this first half life, we know that half of material will be gone.
