All the elements after Uranium(atomic no. 92) have been artificially produced.
Elements that have greater atomic masses then uranium are created using nuclear fission.
Transuranic elements are the elements with an atomic number greater than 92.
The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
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 (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.
All the elements after Uranium(atomic no. 92) have been artificially produced.
Elements that have greater atomic masses then uranium are created using nuclear fission.
Transuranic elements are the elements with an atomic number greater than 92.
Transuranic elements
More electrons, protons, neutrons and a greater atomic weight.
Transuranic elements are the chemical elements with an atomic number greater than 92.
i believe it is 57 do.If im wrong then im wrong im very sorry if i am.

The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
Because no element with an atomic number greater than 92 occurs naturally; any such element is made by transmutation of another element.
The atomic mass is greater.
