The transuranic elements are those with an atomic number greater than 92, the atomic number of uranium. Only neptunium (Atomic number 93) occurs naturally on earth, the rest plutonium americium etc are made artificially. See the wikipedia article http://en.wikipedia.org/wiki/Transuranic_elements
Transuranic elements are elements with atomic numbers greater than uranium (92). They are artificially produced through nuclear reactions and have unstable nuclei, making them radioactive. These elements typically have shorter half-lives and can pose challenges for disposal due to their long-lasting radiation.

Why transuranic element known synthetic elements?
Transuranic elements are known as synthetic elements because they are not found naturally on Earth and must be created in a laboratory through nuclear reactions. These elements have atomic numbers higher than uranium (92) and are generally unstable and radioactive. Scientists have been able to produce transuranic elements by bombarding heavy elements with particles to create new elements.
How has technology helped in production of transuranic elements?
The ability to isolate neutrons, beta and alpha particles has enabled them to be fired at nuclei of atoms at high speeds. The invention of nuclear reactors which can absorb excess neutrons can control nuclear reactions and produce transuranic elements. Also, technological advances in accelerating particles in cyclotrons and particle accelerators has aided the production of transuranic elements.
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.
What is trans-uranium?
Trans-uranium elements are synthetic elements with atomic numbers greater than uranium (92). These elements are produced in laboratories through nuclear reactions and are typically radioactive with short half-lives. Many trans-uranium elements are involved in research and nuclear applications.
What is the family name for neptunium?
Neptunium is a member of the actinoids family.
Why are there no one deposits of transuranic elements on earth?
why are no one deposits of transuranic elements on earth?
What are transuranics?
transuranic elements are all elements with atomic numbers greater than 92, uranium is 92 so transuranic is past uranium
What family is plutonium is from?
Actinides group, transuranic elements, metals, artificial elements
What are elements after unranium?
Those with higher atomic number are called transuranic elements
Is the Curium a heavier element?
Curium is one of the transuranic elements.
What are elements with more than 92 protons called?
Transuranic.

Describes how transuranic elements are produced?
Transuranic elements (elements with a greater atomic no.>92) are produced by the bombardment of large nuclei with neutrons in a nuclear reactor and other small particles (ie. beta and alpha particles) in a particle accelerator.
What is Discovery and production of transuranic elements?
Transuranic elements are those which are heavier than uranium, that is, after uranium (92) in the periodic table (as the name suggests). Uranium is the heaviest naturally occurring element on Earth, hence, elements after Uranium must be synthesised. This synthesis can occur in a nuclear reactor, for example, the bombardment of uranium-238 with neutrons produces the unstable isotope uranium-239 which decays to form the transuranic element neptunium-239, i.e. 238U92 + 1n0 → 239U92 → 239Np93 + 0e-1 Other transuranic elements can be produced by bombarding the nuclei of heavier elements with those of other elements. For example, the production of the transuranic element Bohrium: 20983Bi + 5424Cr → 262107Bh + n Since these transuranic elements are not found naturally the creation of a new transuranic element is a discovery, since it has never before been observed. However, it must be noted that many of these elements have very short half-lives (a couple of seconds) and that when synthesised only a small amount is likely to be produced (in some cases only a few atoms!).

How is mendelevium helpful to man?
It isn't, beyond helping physicists to understand transuranic elements.
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.
