Yes. Plutonium (atomic number: 84) is a trans-uranium element (meaning it has a higher atomic number than uranium (82)). Every element on the Periodic Table after uranium is man-made.

Where are most synthetic elements found on periodic table?
These elements are found after uranium.
What is trans-uranium?
Transuranic elements are the elements with an atomic number greater than 92.
Is uranium synthetic?
No, uranium is a natural chemical element.
How many natural occurring elements in the world?
Exactly 90 that we know of. All the elements 1-92, or Hydrogen (H) through Uranium (U) are natural, with the exception of element 61, Promethium (Pm), and element number 43, Technetium (Tc). Everything past Uranium can only be created through synthetic means.
All synthetic elements have 92 protons?
Only uranium has 92 protons; each chemical element (natural or artificial) has a different number of protons.
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.
Where are most synthetic elements found on periodic table?
These elements are found after uranium.
Why are elements with atomic numbers higher than 92 referred to as transuranium elements?
the atomic number of uranium is 92. the elements after that is thus called trans-uranium (meaning after uranium)
What is trans-uranium?
Transuranic elements are the elements with an atomic number greater than 92.
What is a trans-uranium?
Transuranic elements are the chemical elements with an atomic number greater than 92.
How stable are trans-uranium elements?
Transuranium elements are not stable. See the link below for details.
What elements are considered synthetic elements?
Pretty much all elements after Uranium are synthetic (made by man) Any element above 94 (plutonium and neptunium were also discovered in extremely small concentrations in uranium minerals), are all considered synthetic since they do not occur naturally on the earth, but were made under laboratory conditions.
What makes trans-uranium elements radioactive?
Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
How many unnatural elements are there?
Every transuranic(after uranium) element is synthetic and does not occur in nature.So, there are 26 unnatural elements so far.
Is actinide considered a synthetic element?
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
Is uranium synthetic?
No, uranium is a natural chemical element.
What is the first trans uranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
