Talk:Isotopes of thorium

message: Any theoretical explanation about Th-216 and its instability?
Thorium-216 has a magic number (physics) for neutrons of 126, and thus the atomic mass number of 90 + 126 = 216, yet Th-216 is pretty darned unstable.
The most common and stable isotope of thorium is Th-232, which has 90 protons and 142 neutrons, neither of which is a magic number. On the other hand, lead-208 has magic numbers for both protons and neutrons, 82 + 126 = 208, and bismuth-209 has a magic number for neutrons: 83 + 126 = 209, and it is practically stable.47.215.188.197 (talk) 05:07, 8 March 2017 (UTC)
replies: text: Because all the closed nuclear shells in the world will not save you from being so far from the beta stability line. That doom is governed by the weak force, not the strong force which is related to nuclear shells. Double sharp (talk) 05:22, 15 April 2017 (UTC)

message: Energy of the isomeric transition of 229mTh: 8.3 eV × NA = 800.8 kJ/mol, which is in the order of the energy change in a typical chemistry reaction (for example 2Na + Cl2 → 2NaCl). Does this mean that given 229Th, its isomer can be easily produced? 2A04:CEC0:10F7:4CCE:4D6B:BB75:8017:1D4 (talk) 18:43, 24 February 2024 (UTC)
