Not all nuclear reactions are spontaneous. These reactions occur when stable isotopes are bombarded with particles such as neutrons. This method of inducing a nuclear reaction to proceed is termed artificial radioactivity. This meant new nuclear reactions, which wouldn't have been viewed spontaneously, could now be observed. Since about 1940, a set of new elements with atomic numbers over 92 (the atomic number of the heaviest naturally occurring element, Uranium) have been artificially made. They are called the transuranium elements.
What else can I help you with?
What are examples of artificial radioactivity?
The bombardment of U-235 isotope with a nucleus, releasing tremendous amount of energy.
Who produced the first artificial radioisotope and what other contributions did they make?
Irène Joliot-Curie and Frédéric Joliot produced the first artificial radioisotope in 1934. They also made significant contributions to nuclear physics, winning the Nobel Prize in Chemistry in 1935 for their discovery of artificial radioactivity.
What is a sentence for radioactivity?
Chernobyl is well-known for it's dangerously high radioactivity levels.
Copper can be converted into gold by?
Copper cannot be converted into gold through any scientific process or alchemical transformation. The idea of turning base metals into gold is a concept from medieval alchemy that has no basis in reality.
Who are the scienist contributed about radioactivity?
Marie Curie, Pierre Curie, and Henri Becquerel are notable scientists who made significant contributions to the understanding of radioactivity. Marie Curie's work on radioactivity earned her two Nobel Prizes in Physics and Chemistry.
What is an examples of artificial radioactivity except U?
Uranium is not artificial radioactivity so it is not clear what the question is about.
How does artificial transmutation differ from artificial radioactivity?
"Artificial transmutation" is a nuclear reaction induced in laboratory, its man made. Artificial radioactivity is a radioactive disintegration phenomenon supported by artificial isotopes.
Radioactivity can be what?
Radioactivity can be induced in ordinary matter by artificial transmutation.
What are the differences between natural radioactivity nd artificial radioactivity?
Natural radioactivity occurs spontaneously in certain elements without human intervention, while artificial radioactivity is induced through processes like nuclear reactions or bombardment of nuclei with particles. Natural radioactivity is present in materials like uranium and thorium, whereas artificial radioactivity typically involves isotopes produced in nuclear reactors or accelerators. Both types of radioactivity emit radiation, but the sources and mechanisms differ.
Is natural radioactivity is random and artificial radioactivity is controlled?
Natural radioactivity occurs spontaneously in certain elements, so it is considered random. Artificial radioactivity, on the other hand, is intentionally induced through processes like nuclear reactions and can be controlled to some extent.
Is bombardment of alpha particles on beryllium artificial radioactivity?
Yes, bombarding beryllium with alpha particles can induce artificial radioactivity. When alpha particles collide with beryllium nuclei, the resulting nuclear reaction can produce radioactive isotopes of beryllium, creating artificial radioactivity.
How are hydrates used?
hydrates are mainly used in artificial radioactivity and ............
What did Irene and Fredric Joliot-Curie discover?
artificial radioactivity.
Can copper be converted into gold by artificial radioactivity?
No, copper cannot be converted into gold by artificial radioactivity. While elements can be transmuted through nuclear reactions, the amount of energy required to convert copper into gold is prohibitively high and not practical.
Is the fission of uranium 235 an example of natural or artificial radioactivity?
The fission of uranium-235 is an example of natural radioactivity, as uranium-235 is a naturally occurring radioactive isotope. Artificial radioactivity, on the other hand, refers to the radioactivity induced in a normally stable element through processes like nuclear reactions or particle bombardment.
How did Irène Joliot-Curie contribute to the Atomic Theory?
discovering artificial radioactivity
What is the radioactivity of sodium?
Sodium does not exhibit natural radioactivity. However, artificial radioisotopes of sodium can be produced in a laboratory setting through nuclear reactions.
