Click here to get an answer to your question ✍️ The half - life of ^238 U for alpha - decay is 4.5 × 10^9 years. The number of disintegration per second occur   Major radioactive elements used for radiometric dating. Parent, Daughter, Half Life(years), Dating Range(years), Minerals/materials. Uranium-238, Lead  The radioactive isotopes uranium-238 (U-238) and thorium-232 (Th-232) have decay times (half-lives) which are comparable with, or larger than, the age of the   7% of naturally occurring uranium, and essentially all the rest is U-238. Both U- 235 and U-238 spontaneously decay, with half-lives given below.

In the case of uranium-238, the process has a very low probability, requiring more than 10 15 years for half of the material to be transformed (its so-called half-life… Question: The Half-life For The Radioactive Decay Of U−238U−238 Is 4.5 Billion Years And Is Independent Of Initial Concentration. Part A How Long Will It Take For 17 %% Of The U−238U−238 Atoms In A Sample Of U−238U−238 To Decay?

Since the half-life of U-238 is 4.5 Billion years, this rock must be 9 BY old. 1d. If you find a rock  Neptunium-238 has a half-life of 2.1 days and decays into plutonium -238 reactor contains within its uranium fuel load about 325 kilograms of plutonium, with. Uranium undergoes radioactive decay very slowly. The half-life for U238 is 4.5 billion years. After one half-life, a container that originally held 10,000 kg of pure U  Task. Uranium 238 is a radioactive material with many applications in nuclear technology.

A zircon crystal is found to have 12.5% U-238 and 87.5% Pb-206. How many half-lives has the Uranium gone through? Please Since 238 U has a half-life of 4.5 × 10 9 y, it is useful for dating only very old materials, showing, for example, that the oldest rocks on Earth solidified about 3.5 × 10 9 years ago.

[2] The half-life of U-238 is 4.468 x 109yr. 1.3 x 108yr / 4.468 x 109yr = 0.029098 (this is how many half-lives have elapsed) (1/2)0.029098= 0.9800 (this is the decimal amount of U-238 remaining) 3.25 mg is to 0.98 as x is to 1 Half-life of uranium 238 is ~4.5×109 years.
