Question:

²³⁸U is long-lived but ultimately unstable; it will eventually spontaneously break into two fragments, a ⁴He nucleus and a ²³⁴Th nucleus, in a process called alpha decay, which we'll learn about in the next section. A great deal of energy is released in the process. What must be true about the masses of the nuclei involved? image text in transcribed
