What is the approximate half-life of uranium-238?
The approximate half life of Uranium 238 is 4.5 x 109 years.
What is the final product of uranium 238?
Uranium 238 is a natural isotope of uranium, non-fissionable with thermal neutrons, with an atomic mass of 238,050 788 247 ± 0,000 002 044 u.a. and a half life of 4,468 x 109 years, atomic number 92. Natural uranium contain 99.2745 % U 238 (atomic); the desintegration of U 238 is alpha type.
The characteristic of the radioactive isotope uranium-238 that makes this isotope useful for accurately dating the age of a rock is the isotope's BLANK?
The characteristic of the uranium-238 isotope that makes it useful for dating rocks is its long half-life of about 4.5 billion years. This allows for accurate dating of rocks that are billions of years old.
Examples of radioisotope and their half life?

Hydrogen-3, which is commonly called tritium, has a half life of 12.32 years. Xenon-135 has a half life of 9.14 hours. Silicon-27 has a half life of 4.16 seconds. Lead-180 has a half life of 0.0045 seconds. Copper-54 has a half life of less than 0.000000075 seconds.
What is halflife of uranium?
Uranium has 29 natural and artificial isotopes. Each isotope has his specific half life; for the natural isotopes the half lifes are: U 234: approx. 2.45 x 105 years U 235: approx. 7.04 x 108 years U 238: approx. 4.46 x 109 years
What is the approximate half-life of uranium-238?
The approximate half life of Uranium 238 is 4.5 x 109 years.
How do you write half life of uranium 238 as a standard number?
The half-life of the isotope uranium-238 is 4 468 000 000 years.
What is the half life of uranium 238?
The half-life of uranium-238 is about 4.5 billion years. This means that it takes 4.5 billion years for half of a sample of uranium-238 to decay into thorium-234.
What are the half lives for uranium-235 and uranium-238?
The half-life of uranium-235 is approximately 703.8 million years, while the half-life of uranium-238 is approximately 4.5 billion years.
What is the half life of uranium in common form?
The most common form of uranium is uranium-238, which has a half-life of about 4.5 billion years. This means that it takes 4.5 billion years for half of a sample of uranium-238 to decay into lead-206.
Which radioactive element has a half-life of 4.5 billion years?
Uranium
What type of radioactive decay result in uranium -238 becoming thorium 234.?
This is an alpha decay.The half-life of uranium-238 is 4,468.10ex.9 years.
How long can radioactivity be on uranium?
Radioactivity can persist on uranium for billions of years, as uranium has a very long half-life. The most common isotope of uranium, uranium-238, has a half-life of about 4.5 billion years. Uranium-235, another isotope, has a shorter half-life of about 700 million years.
What is uranium-238's half-life?
4.47 billion years
Find the age of a sample and half life of uranium 238?
The half-life of 238U is 4,468x109 years.
How much time takes uranium decays into led?
It takes billions of years for uranium to decay into lead. Uranium-238, the most common isotope of uranium, has a half-life of about 4.5 billion years, meaning it takes that long for half of a sample of uranium-238 to decay into lead-206.
How many half lifes has uranium 238 undergone if it crystallized at the same time earth formed?
Uranium-238 has a half-life of about 4.5 billion years. The Earth is estimated to be about 4.5 billion years old, so if uranium-238 crystallized at the same time the Earth formed, it would have undergone approximately one half-life since then. This means that about half of the original amount of uranium-238 would remain today.
