I think you mean Uranium /U/.
Uranium 235 or Plutonium 239
No, Uranium is a rare-ish element whose radioactive isotope is often used in nuclear reactors. ingestion of radioactive elements can result in death
Synthetic elements are those elements that are not naturally occurring on earth, but rather have been synthesized in a nuclear reactor. They are often radioactive with short halflifes.
Uranium. Most current power reactors use Uranium enriched to 3% Uranium-235.
No. The most common isotope(s) of an element are often stable.
Uranium
natural isotope of gold is 197 and he is stable element and not with radioactive decay why the gold ingot are often associated with age?
Uranium 235 Plutonium
A stable, nonradioactive atom must be formed.
When we use the term radioisotope, this means an isotope of an element that emits radiation, whether alpha, beta, or gamma in nature. Sometimes an element that is found in nature is not radioactive, but an isotope that is artificially produced by exposing the element to neutrons in a reactor, can often be found to be radioactive, because an extra neutron has been added to the nucleus. The nucleus has the same number of protons so is the same element, but the nucleus is now unstable and has become radioactive. Not all elements behave the same way. If you look up a particular element in Wikipedia you will find if it has radioisotopes in the details, and what sort of nuclear radiation is produced.
No. You have to change the number of protrons.(Changing the number of neutrons changes the isotope of the element, but it is still the same element. However, changing the number of neutrons will often result in instability, causing a radioactive decay sequence, which often results in a change in element.)
The most often used radioactive elements used in radiometric dating are carbon, potassium-argon and uranium-lead.Other elements are not, or very rarely used.
