The element Michellium (Mi) does not exist. But if it did, it would have the following isotopic abundances: Isotope Atomic Mass  % Natural Abundance  83Mi      83.14 amu    14.6 %  83Mi      84.92 amu   Assuming that Michellium only has two naturally-occurring isotopes, what is the atomic weight of Michellium?

Visible/UV emission spectroscopy can be used to identify the presence of elements in an unknown sample. Some characteristic wavelengths of common elements are shown below: Ag: 328.1 nm        Fe: 372.0 nm Au: 267.6 nm       K: 404.7 nm Ba: 455.4 nm        Mg: 285.2 nm Ca: 422.7 nm        Na: 589.6 nm Cu: 324.8 nm       Ni: 341.5 nm If an unknown sample is burned and emits light with a frequency of 5.088 x 1014 Hz, which element above is most likely present in the sample?

The element Titotium (Tt) was recently discovered in a remote village in Mexico. Tt is composed of two naturally occurring isotopes: 295Tt and 301Tt, with atomic masses of 294.969 and 301.002 g/mol respectively.  295Tt is the most common isotope, with a natural abundance of 63.84%.  Which entry below should be used when Titotium is added to the Periodic Table later this year?
