Consider a nucleus that undergoes a decay. greater than less than O equal to Submit Request Answer Part B Choose the best explanation from among the following: O The decay adds an alpha particle to the nucleus, causing its radius to increase. An a decay leaves the number of nucleons unchanged. As a result, the radius of the nucleus stays the same. When the nucleus undergoes decay it ejects two neutrons and two protons. This decreases the number of nucleons in the nucleus, and therefore its radius will decrease. Submit Request Answer
