The product of -decay is easy to predict if we assume that both mass and charge are conserved in nuclear reactions.Alpha decay of the The sum of the mass numbers of the products (234 4) is equal to the mass number of the parent nuclide (238), and the sum of the charges on the products (90 2) is equal to the charge on the parent nuclide.- Law of Superposition, Principles of Original Horizontality & Cross-Cutting Relationships.Already planning for taking relative fossil dating definition place on the dialogue.
