What else can I help you with?
Which two elements are lighter than uranium and are both produced artifically?
You think to prometium and technetium; but today these chemical elements are considered as being natural.
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
Why are artificially produced radioisotopes not found in nature?
Artificially produced radioisotopes are not found in nature because they are created through nuclear reactions in laboratories or nuclear reactors, which do not occur naturally. These isotopes often have short half-lives and decay into stable elements relatively quickly, making them difficult to detect in natural environments. Additionally, the specific conditions required for their synthesis are not commonly found in nature.
How are elements with atomic masses greater than uranium made?
Elements with atomic masses greater than uranium are typically produced in supernova explosions, where high-energy processes enable the fusion of heavy nuclei. This process can lead to the creation of transuranic elements such as neptunium, plutonium, and beyond. Additionally, elements beyond uranium can also be artificially synthesized in particle accelerators through nuclear reactions involving target nuclei.
What isotopes of plutonium are natural?
Plutonium has no natural isotopes. All plutonium isotopes are artificially produced through nuclear reactions.
Is it possible to make helium artificially?
Yes, helium can be artificially produced through nuclear reactions or by extracting it from natural gas deposits.
Which two elements are lighter than uranium and are both produced artifically?

Where is copernicium found?
Copernicium is an artificial chemical element.
Chemical elements with atomic numbers greater than that of uranium are called?
Transuranium elements. They typically have atomic numbers higher than 92 (uranium's atomic number) and are all artificially produced through nuclear reactions.
Can silver be artificially created?
Yes, silver can be artificially created through a process called silver synthesis, where silver atoms are produced in a laboratory setting using various methods such as chemical reactions or nuclear reactions.
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
What elements are produced in the sun?
From hydrogen, isotopes of helium are formed through nuclear reactions.
What are elements that can not be found on earth and can be created called?
Elements that cannot be found on Earth naturally but can be created artificially are called synthetic elements. These elements are typically produced in laboratories through nuclear reactions or particle accelerators. Examples of synthetic elements include technetium and americium.
Why can elements be produced in the sun but not in Earth's atmosphere?
Elements can be produced in the sun through nuclear fusion reactions, which require extremely high temperatures and pressures. These conditions are not present in Earth's atmosphere, so elements are not produced in the same way here. Elements on Earth are primarily produced through processes like supernova explosions and nuclear reactions in labs.
What is a trans-uranium?
Trans-uranium elements are elements that have atomic numbers greater than uranium (atomic number 92). These elements are artificially produced in nuclear reactions and are typically highly radioactive. Examples include neptunium, plutonium, and americium.
Is it possible to artificially produce helium?
Yes, it is possible to artificially produce helium through nuclear reactions, such as in nuclear reactors or particle accelerators.
Why are artificially produced radioisotopes not found in nature?
