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.
What elements are synthetic elements?
Sythetic elements are those with half lifes to small to be found in nature, they are manmade and generally fairly unstable. The synthetic elements are: All elements with atomic numbers 1 through 98 are naturally occurring at least in trace quantities, but the following elements are usually produced through synthesis. Except for francium, they were all discovered through synthesis before being found in nature.Element nameChemical SymbolAtomic NumberFirst definite discoveryTechnetiumTc431936PromethiumPm611945AstatineAt851940FranciumFr871939NeptuniumNp931940PlutoniumPu941940AmericiumAm951944CuriumCm961944BerkeliumBk971949CaliforniumCf981950 The following elements do not occur naturally on Earth.

What does elements with a higher atomic number than uranium have?
Elements with a higher atomic number than uranium belong to the transuranium elements, which are all man-made and generally unstable due to their high atomic numbers. These elements typically undergo radioactive decay, leading to the formation of lighter elements.
How do transuranium elements differ from other inner transition metals?
Transition metals are d-block elements. Their general electronic configuration is (n-1)d1-9 ns0-2. The last electron enters the d-subshell.Inner Transition metals are f-block elements. Their general electronic configuration is (n-2)f1-13(n-1)d1-9 ns0-2. The last electron enters the f-subshell.
Why are elements with atomic numbers higher than 92 referred to as transuranium elements?
Elements with atomic numbers higher than 92 are referred to as transuranium elements because they are synthesized artificially by nuclear reactions and do not occur naturally in significant quantities on Earth. They generally have unstable nuclei and are radioactive, making them distinct from the naturally occurring elements in the periodic table.
Are actinoids all transuranium elements?
No, actinoids are a group of elements that include both transuranium elements (elements with atomic number greater than 92) and non-transuranium elements. Transuranium elements are specifically those that have atomic numbers higher than uranium (92).
What are elements with atomic numbers above 95 called?
These elements (neptunium and heavier) are called transuranic elements or trans-uranium elements. They could also properly be called artificial and radioactive.*Both plutonium and neptunium, first known through synthesis, have been found to occur naturally in trace amounts, along with americium, curium, berkelium and californium. These occur through a natural version of the synthesis process, within quantities of uranium ore.
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.
Synthetic elements are found in what group?
Synthetic elements are found in the group of transuranium elements, which are elements with atomic numbers higher than uranium (92) on the periodic table. These elements are artificially created in a laboratory through nuclear reactions and have unstable nuclei.
Any element with an atomic number greater than 92 is?
An element with an atomic number greater than 92 is considered a transuranium element. These elements are artificially created in a laboratory and are generally unstable, undergoing radioactive decay. Examples include neptunium, plutonium, and americium.

Is it true that elements with atomic numbers greater than 92 can only be found in a science lab?
Yes, elements with atomic numbers greater than 92 are considered transuranium elements and are typically only produced in laboratories through nuclear reactions. These elements are highly unstable and have short half-lives, making them extremely rare in nature.
Why are elements with atomic numbers higher than 92 referred to as transuranium elements?
Elements with atomic numbers higher than 92 are referred to as transuranium elements because they are synthesized artificially by nuclear reactions and do not occur naturally in significant quantities on Earth. They generally have unstable nuclei and are radioactive, making them distinct from the naturally occurring elements in the periodic table.
What are super heavy elements?
Super heavy elements are elements with atomic numbers greater than 104. They are synthetic and do not occur naturally on Earth. These elements are typically produced in laboratories through nuclear reactions involving heavy isotopes.
How many transurnic elements are discovered so far?
There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.
