The Unending Journey of the Periodic Table

TLDRDespite appearing full, the periodic table is not yet complete, and there is still potential for new elements beyond the current 118. The prediction that elements could not have an atomic weight larger than 256 has been proven wrong, and the limit may be higher. Richard Feynman's estimate of an atomic number limit of 137 may also be incorrect, with the possibility of an end around 173. While elements become increasingly unstable at higher atomic numbers, there are predictions of stability islands that could extend the periodic table even further.

Q&A

Is the periodic table considered complete with 118 elements?

No, the periodic table is not considered complete with only 118 elements. There is potential for new elements beyond the current number.

Has the prediction of an atomic weight limit of 256 been proven wrong?

Yes, the prediction that elements could not have an atomic weight larger than 256 has been proven incorrect.

Is there a limit to the atomic numbers of elements?

The limit to atomic numbers is still uncertain. While Richard Feynman estimated a limit of 137, it may be higher, possibly around 173.

Why do elements become more unstable at higher atomic numbers?

As atomic numbers increase, elements tend to become more unstable due to the increased forces within the nucleus.

Are there any predictions of stability islands in the periodic table?

Yes, there are predictions of stability islands that could extend the periodic table, allowing for more stable elements.
