WebThis makes beta decay a great example of how nuclear reactions can eerily transform one substance into another. The product potassium chloride is commonly sold as a salt-substitute in grocery stores. This product contains trace amounts of potassium-40 (K), which tends to undergo beta decay into calcium-40 (Ca). WebIn alpha decay, an alpha particle is ejected from an unstable nucleus, so here's our unstable nucleus, uranium-238. An alpha particle has the same composition as a helium nucleus. …
Webβ-decay: When a radioactive nucleus disintegrates by emitting a β-particle, the atomic number increases by one and the mass number remains the same. β-decay can be expressed asZX A→ Z+1Y A+ −1e 0Example : Thorium ( 90Th 234) is converted to protoactinium ( 91Pa 234) due to β-decay90Th 234→ 91Pa 234+ −1e 0.

Thorium is a naturally occurring radioactive element that was discovered in 1828 by J. J. Berzelius. [1] It is considered to be "fertile", due to its ability to be converted into a fissile material from neutron absorption and later nuclear decay.
