Thorium 238

All but two elements up to bismuth (element 83) have an isotope that is practically stable for all purposes ("classically stable"), with the exceptions being technetium and promethium (elements 43 and 61). All elements from polonium (element 84) onward are measurably radioactive. Th is one of the two nuclides beyond bismuth (the other being U) that have half-lives measured in billions of … WebProtons and Neutrons in Thorium. Thorium is a chemical element with atomic number 90 which means there are 90 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 …
