FAQ
Frequently Asked Questions
No, all transactinide elements are synthetic (man-made) and do not occur naturally on Earth in measurable quantities.
Actinides are the 15 elements from actinium (89) to lawrencium (103). Transactinides are all the elements with atomic numbers greater than 103, positioned 'beyond' the actinides on the periodic table.
No. They are produced atom-by-atom, are extremely radioactive, and have very short half-lives (often milliseconds or less), decaying before any macroscopic quantity could accumulate.
They test the limits of the periodic table and nuclear stability, help validate theoretical models in nuclear physics, and may lead to discoveries about 'islands of stability' where some superheavy elements could be less unstable.
Any chemical element with an atomic number greater than 103 (lawrencium).
Transactinide element is usually technical/scientific in register.
Transactinide element: in British English it is pronounced /ˌtrænzˈæk.tɪ.naɪd ˌel.ɪ.mənt/, and in American English it is pronounced /ˌtrænzˈæk.tə.naɪd ˌel.ə.mənt/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think 'TRANS-Atlantic' - these elements are beyond ('trans') the ACTINIDE series on the periodic table, sailing into unknown waters.
Conceptual Metaphor
THE PERIODIC TABLE IS A MAP / A FRONTIER. Transactinide elements are the 'uncharted territory' or the 'far frontier' of this map.
