Thorium 234 is an artificial isotope of uranium (half life 24,1 days).
Uranium 238 emits an alpha particle to become Thorium 234.
Uranium 238........alpha particle........Thorium 234
1. Uranium 238 is transformed in thorium 234 by alpha decay. 2. Uranium 235 is transformed in thorium 231 by alpha decay. 3. Uranium 234 is transformed in thorium 230 by alpha decay.
The decay product of uranium-238 is thorium-234.
Uranium-238 emits an alpha particle and becomes thorium-234.
This is the equation for the radioactive decay of uranium-238:U-238-------------------Th-234 + He
The isotope thorium-234 is obtained first.
It is thorium 234.
Uranium 238 is transformed in thorium 234 by alpha decay.
- After alpha disintegration the isotope uranium-238 is transformed in the isotope thorium-234. - After alpha disintegration the isotope uranium-235 is transformed in the isotope thorium-230. Platinum is a misspelling ?
All radioactive isotopes decay because they are unstable; uranium-238 decay to thorium-234 by beta (-) decay. The half life of 238U is very great: 4,468.109 years.
