Unformatted text preview: Z f = Z i + 3∆ Z α + 2∆ Z β and A f = A i + 3∆ A α . Referring to Appendix F or G, we ±nd Z i = 93 for Neptunium, so Z f = 93 + 3( − 2) + 2(1) = 89, which indicates the element Actinium. We are given A i = 237, so A f = 237 + 3( − 4) = 225 . Therefore, the ±nal isotope is 225 Ac....
