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.
