What is the decay product of uranium-238?
U-238 is the most abundant (99.3%) of the three naturally occurring isotopes of Uranium. The other two are U-235 and U-234.U-238 decays spontaneously to Thorium-234 by alpha particle emission. This decays by beta decay to Protactinium-234 and then that undergoes beta decay to become U-234.There are many more decay steps by alpha and beta emission. The end result is Lead-206 which is stable.The full path can be found in the Argonne National Laboratories Human Health Fact Sheet, August 2005, titled Natural Decay Series: Uranium, Radium, and ThoriumThis is found at:http://www.ead.anl.gov/pub/doc/natural-decay-series.pdf
Are most isotopes stable?
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
If the half-life of uranium 235 is 700 million years and have 64 atoms of it how many 700-million-year units of time will pass before 1 atom of uranium 235 is left?
It would take 1.4 billion years for half of the 64 atoms of uranium-235 to decay, leaving 32 atoms. Then another 700 million years would pass for half of the remaining 32 atoms to decay, leaving 16 atoms. This process continues until only 1 atom is left, which occurs after 5 half-lives or 3.5 billion years.
Reaction involving uranium atoms?
Uranium atoms can undergo nuclear reactions such as fission, where the nucleus splits into smaller nuclei, releasing a large amount of energy. This process is the basis for nuclear power plants and atomic bombs. Uranium atoms can also undergo radioactive decay, emitting alpha, beta, or gamma radiation in the process.
What is stable elements?
Unstable elements are radioactive elements that spontaneously decay into other elements. Some are: Radon Uranium Plutonium See the related link for an article giving greater detail on isotope stability.
How many years will it take for 10 g of radioactive uranium to decay into 5 g of radioactive uranium?
It would take one half-life for the 10 g of uranium to decay into 5 g. The half-life of uranium is around 4.5 billion years, so it would take approximately 4.5 billion years.
What causes Uranium to be radioactive?
Uranium is radioactive because it is an unstable element with a nucleus that can undergo radioactive decay. During this decay process, uranium releases energy in the form of alpha, beta, or gamma radiation as it transforms into other elements over time. This radioactive decay is what makes uranium useful for nuclear energy and weapons.
When does Uranium-235 become unstable?
Uranium 235 is unstable because it is a radioactive isotope. This means that it is constantly decaying and emitting radiation. The reason it is unstable is because it has too many neutrons in its nucleus. The neutron is a unstable particle, and when there are too many of them in one place, they can cause problems. When uranium 235 decays, it emits alpha particles, which are high-energy particles that can damage DNA and cause cancer.
What does uranium become when it decays?
If we use uranium-238 as our starter isotope, what happens is that a nuclear decay event happens (in this case an alpha decay) and the U-238 transforms into a daughter isotope thorium (Th-234). The half-life of this transition is 4.5 billion years. Thorium-234 then undergoes a decay. And the process continues until a stable isotope is created as the last daughter of a decay chain. Note that there will be different half lives for the transition events, and the modes of decay will vary depending on what daughter is now the parent in the next decay event. Use the link below to see all the steps. The chart will show the whole chain including the half-life of isotope undergoing decay, the decay mode, and the daughter. Follow along using the keys and the process will reveal itself.
What is more radioactive than pure uranium?
Many radioactive isotopes are more radioactive than the naturally occurring uranium isotopes:All fission product isotopes are more radioactive (e.g. iodine-131, strontium-90)Most radioactive isotopes in the uranium --> lead decay chain are more radioactive (e.g. radium, radon, polonium)Plutonium is more radioactiveTritium is more radioactiveCarbon-14 is more radioactiveArtificially produced uranium isotopes are more radioactive (e.g. uranium-233, uranium-236)etc.
How many radioactive isotopes does uranium have?
All of them.

How many radioactive isotopes are there in Zirconium?
Zr 94: half life 1,1.1017 years, double beta decay Zr 96: half life 2,0.1019 years, double beta decay
How many years would it take radioactive decay in a kilogram of granite to produce this many joules?
The time it takes for radioactive decay in a kilogram of granite to produce a specific amount of energy in joules depends on the specific radioactive isotopes present in the granite, as different isotopes have different decay rates. Granite typically contains trace amounts of uranium, thorium, and potassium isotopes, which decay at different rates and produce different amounts of energy. Detailed calculations would be needed to determine the exact time based on the specific isotopic composition and decay rates in the granite sample.
How many different elements appear in the decay chain?
Common elements in a decay chain include uranium, thorium, radium, radon, and polonium. These elements undergo radioactive decay to produce different isotopes and elements through a series of transformations.
How many isotopes of polonium are part of the decay?
Each isotope has a specific radioactive decay.
