Ununennium
, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119.
What properties would element 119 have?
Element 119 is expected to be a
typical alkali metal with a +1 oxidation state
. The energetic properties of its valence electron, the 8s electron, suggest that its first ionization potential will be higher than the oxidation potential predicted by simple extrapolation, so that the…

Is Element 120 possible?
Unbinilium
, also known as eka-radium or simply element 120, is the hypothetical chemical element in the periodic table with symbol Ubn and atomic number 120. … Unbinilium has not yet been synthesized, despite multiple attempts from German and Russian teams.
Is element 140 possible?
As of 2020, no elements with an atomic number greater than 118 has successfully incorporated. … 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
.
Are there 126 elements?
Unbihexium, also known as element 126 or eka-plutonium, is the hypothetical chemical element with atomic number 126 and placeholder symbol Ubh.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element
astatine

|---|
Is Ununennium radioactive?
Trivia. Although
Ununennium is less radioactive
, it still decays into Tennessine.
What is the highest element number?
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.
What would element 120 be like?
Element 120 is expected to be a
typical alkaline-earth element
. As with element 119, the ionization energies should be higher than the normal family trend would indicate and should make the metallic and ionic radii smaller. These changes should make the chemistry of element 120…
What is the largest possible element?
Thus, helium is the smallest element, and
francium
is the largest.
Is element 118 real?
Oganesson
is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal. It is a member of the noble gas group. … In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) approved the name oganesson for element 118.
Has element 118 been discovered?
In
January 2016
the discovery of element 118 was recognized by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP).
What is Murinite?
Murinite was
a mineral which could be found on Rigel IV
. The Hill People of the Argus River region on Rigel IV used murinite to make the handles of a type of knives which they produced; one such weapon was involved in a series of murders on Argelius II in 2267. ( TOS: “Wolf in the Fold”)
