Only uranium has 92 protons; each chemical element (natural or artificial) has a different number of protons.
92
Protons of all chemical elements are similar. All the isotopes of uranium have 92 protons.
It is natural. All elements with atomic numbers 92 and lower are naturally occurring.
These elements are found after uranium.
Technetium, Tc, and promethium, Pm
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
92
Elements with more than 92 protons are called Transuranic elements.
Protons of all chemical elements are similar. All the isotopes of uranium have 92 protons.

radioactive.
Transuranic.
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.
It is natural. All elements with atomic numbers 92 and lower are naturally occurring.
These elements are found after uranium.
Elements having more than 92 protons, the atomic number of uranium, are called transuranium elements.
235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
