Thorium-228 Th is an isotope of thorium with 138 neutrons. It was once named Radiothorium, due to its occurrence in the disintegration chain of thorium-232. It has a half-life of 1.9116 years. It undergoes alpha decay to Ra. Occasionally it decays by the unusual route of cluster decay, emitting a nucleus of O and … See more Thorium (90Th) has seven naturally occurring isotopes but none are stable. One isotope, Th, is relatively stable, with a half-life of 1.405×10 years, considerably longer than the age of the Earth, and even slightly longer than the … See more 1. ^ Th – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits.

In many countries the use of thorium in consumer products is banned or discouraged … See more Thorium is a weakly radioactive metallic chemical element with the symbol Th and atomic number 90. Thorium is silvery and tarnishes black when it is exposed to air, forming thorium dioxide; it is moderately soft and malleable and has a high melting point. Thorium is an electropositive actinide whose chemistry is dominated by the +4 oxidation state; it is quite reactive and can ignite in air wh…
WebA nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy. Write a nuclear equation: Uranium-235 undergoes alpha decay to produce Thorium-231. 235/92 U ---> 4/2 He + 231/90 Th. Write a nuclear equation: Lanthanum-144 becomes cerium-144 when it undergoes a beta. WebOne example of a radioactive decay series is the sequence of decays that starts with Thorium-232 which ends up as Lead-208. What we mean is that Thorium-232 decays into Radium-228 plus an alpha particle. That isotope of Radium subsequently decays into Actinium-228 via beta decay, and so on until Lead-208 is the final end product.
