Radium 225 --> Radon 222 + Helium 4 Radioisotopes are different elements that have different isotopes Parent elements are the elements that are radioactively decayed Daughter elements are the product that are radioactively decayed In exponential decay , each component has a characteristical half-life, which is the time it takes for a parent to become a daughter Ways to Generate Energy 1.
