Names have yet to be proposed for elements 113, 115, 117, and 118 and so those used here are IUPAC's temporary systematic names (Pure & Appl. Chem., 1979, 51, 381-384). In some countries, the spellings aluminum, cesium, and sulphur are usual. Atomic weights (mean relative masses): these are IUPAC 2009 values (M.E. Wieser and T.B. Copien, Pure & Appl. Chem., 2011. 83, 359). The last significant figure of each value Is considered reliable to *1 except where a larger uncertainty is given In parentheses. Representative values for those elements having an atomic weight Interval are given (H, U, B, C, N, 0, SI, S, CI, TI). Elements with values given in [brackets] have no stable nuclides and are represented by 5 s.f. values for the longest-lived isotope given in thelupac 2009 values.
