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

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

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.
Radioactive decayNuclear fissionHalf-lifeCosmic ray
