What are two synthetic elements with atomic numbers less than 92?
Technetium, Tc, and promethium, Pm
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.
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 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 are the elements in a synthetic diamond?
Carbon

Do all synthetic elements have more than 92 elements?
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
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.

What are elements that are made in lab called?
Elements that are made in a laboratory are typically referred to as synthetic elements. These elements are not found naturally on Earth and are produced by scientists through various experimental methods. Examples of synthetic elements include einsteinium and seaborgium.
Synthetic elements are formed by experimentation?
Yes, all synthetic elements are man made.
Is it true that transuranium elements are synthetic elements with atomic numbers greater than 92?
Yes. All elements classified after Element Atomic Number 92 (Uranium) (id est transuranium) are synthesised elements and can not be found naturally. They are also all radioactive, although this is the case for elements from elements 84 onwards.
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.
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.
What are elements called that are created by main in a laboratory?
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.
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 elements are radioactive and synthetic?
einsteinium,......
