Question 4: ________, the heaviest member, portrays a switch from the +IV state to the +II state.

Question 5: ________ represents the point at which the stability of the +II and +IV states are similar.

Question 6: ________: Ununquadium–Unbinilium–Unbihexium
Island of stabilityRadonTable of nuclides (combined)Uranium

Question 7: Due to the expected high fission barriers, any nucleus within this island of stability will exclusively decay by alpha-particle emission and as such the nucleus with the longest ________ is predicted to be 298114.

Question 8: The isotopes of ununquadium have also been observed in the decay of elements 116 and 118 (see ________ for decay chain).

Question 9: This means that such nuclei are spherical in their ground state and should have high, wide fission barriers to deformation and hence long SF partial ________.
