What is the final nuclide that results from a succession of nine alpha emissions, followed by six beta emissions, beginning with Plutonium 244, 244Pu?

Answer 1

Answer When nucleus emits &- particles, then it decreases the atomic number by 2 and mass number of nucleus by 4 unit that is it emits he. When nucleus emits ß- particles, then the atomic number of nucleus is increased by 1 unit while, there is no change in mast number .C _ip) zuhpu a 240 a, 236 go 232 88 -Ra Th T > 228 86 94 Rn 92U L 208 os 220 ๆ KT 212 78 Pь 82 ng 'Po 84 el 216 so Kg 76 HP 208 Р ² 208 B, 20871 81 208 77 208 PE Ir ß, 245 7g Au 80 Hg 다. 208 82 Pb Hence, final nuclide that rerut from a successive of nine alpha iemissions, followed by six beta emisopas, begining with plutonium-ahh is lead- 208 i-e Pb 208 82
