In chemistry, a transuranic element receives a permanent name and symbol only after its synthesis has been confirmed.
In some cases, such as the Transfermium Wars, controversies over the formal name and symbol have been protracted and highly political.
The temporary names derive systematically from the element's atomic number, and apply only to 101 ≤ Z ≤ 999.
The systematic symbol is formed by taking the first letter of each root, converting the first to uppercase.
As of 2019[update], all 118 discovered elements have received individual permanent names and symbols.
