Is element 140 possible?

However, extended periodic table theories predicted about chemical elements beyond these 118 elements. According to this, Corbomite (Ct) is a chemical element with atomic number 140. However, in real-life science, element 140 has yet to be identified.

Is there a 119th element?

Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.

Is Element 120 possible?

Ununennium and unbinilium (elements 119 and 120) are the elements with the lowest atomic numbers that have not yet been synthesized: all the preceding elements have been synthesized, culminating in oganesson (element 118), the heaviest known element, which completes the seventh row of the periodic table.

What is the highest element possible?

Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since 2005, only five (possibly six) atoms of the isotope oganesson-294 have been detected.

Is element 138 possible?

Untrioctium, Uto, is the temporary name for element 138. Isotopes are predicted in the bands 451Uto to 395Uto, 371Uto to 365Uto, and 359Uto. There may be isotopes in the band from the neutron dripline to 452Uto, but it is not possible to predict which ones are possible.

What is the last possible element?

Uranium, with an atomic number of 92, is the last element stable enough to occur naturally on Earth. Every element beyond it has a nucleus that falls apart quickly, and their half-lives—the time it takes for half of the material to decay—can be minutes, seconds or even split seconds.
