The most common isotope of uranium is U-238. It decays by the
emission of an alpha particle.
The mineral pitchblende is a major source of uranium
After an alpha particle is emitted, how many protons are found in
U-238's daughter isotope?



Answer :

GinnyAnswer

Final answer:

When uranium-238 emits an alpha particle, it transforms into thorium-234, resulting in a decrease of two protons.


Explanation:

After uranium-238 emits an alpha particle, it transforms into thorium-234 as the daughter isotope. The alpha particle contains two protons and two neutrons, leading to a decrease in the atomic number of the parent nucleus. In the case of U-238 decaying to thorium-234, the number of protons reduces by two.
