When uranium undergoes alpha decay, it emits an alpha particle (which consists of 2 protons and 2 neutrons) and transforms into thorium. The mass of the thorium produced can be determined by subtracting the mass of the emitted alpha particle from the original mass of the uranium nuclide. The specific mass of thorium will depend on the isotope of uranium that is decaying, but it generally corresponds to the mass number of the uranium minus 4 (for the alpha particle).
When uranium radiates alpha particles, it transforms into thorium. Thorium is a radioactive element that is produced as a result of the decay of uranium through alpha emission.
You get this answer by performing the following: Mass # Mass # 4 Atomic # Parent symbol -> Atomic # Daughter symbol + 2 He 238 234 4 92 U -> 90 Th + 2 He Both sides must equal the same thing, so if you figure out what plus 4 = 238 and what plus 2 = 92, you can figure out the element is formed through decay. The resulting element in this case is Thorium.
Uranium-235 decays primarily through alpha decay, where it emits an alpha particle (helium nucleus) and transforms into thorium-231.
This is an alpha decay.The half-life of uranium-238 is 4,468.10ex.9 years.
Thorium-230 decays into radium-226 when it emits an alpha particle.
When thorium-230 decays by emitting an alpha particle, it transforms into radium-226. This decay process reduces the mass number by 4 and the atomic number by 2.

When uranium radiates alpha particles, it transforms into thorium. Thorium is a radioactive element that is produced as a result of the decay of uranium through alpha emission.
Alpha emission means a He (A=4, Z=2) core is released along with energy. Helium's atomic number is 2 and the atomic mass is 4. So when Thorium (A=x, Z=90) emits an alpha particle it becomes a Radium (A=x-4, Z=88). By the way: Thorium is very vague when it comes to nuclear physics. It's important to state the atomic mass of the atom. There exist many forms of each element, called isotopes.

The balanced equation for the alpha decay of thorium-229, Th-229, is: Th-229 -> Ra-225 + He-4 This equation shows that a thorium-229 nucleus undergoes alpha decay to form a radium-225 nucleus and a helium-4 particle.
