Element names without suffixes

Standard element name without suffixes

  • Use the standard element name for the following:
    • -elements by themselves (in the zero oxidation state),
      • NOTE: some are diatomic elements (H2, O2, N2, Cl2, Br2, I2, F2):
        • Examples:
          • Ag = silver
          • F2=fluorine
        • Other Examples:
          • Ag, Al, As, Au, B, Ba, Bi, Br2, C, Ca, Ca, Cl2, Co, Cr, Cs, Cu, F2, Fe, H2, He, Hg, I2, K, Li, Mg, Mn, N2, Na, Ni, O2, P, Pb, Rb, S, Se, Si, Sn, Sr, Te, Zn
        • Worksheet:Study Aid A
    • -monatomic CATIONS that stand alone as the ion: follow the element name with the word “ion”. All are metals (or hydrogen).
      • NOTE: variable oxidation states need a Roman Numeral in the NAME, NOT in the formula!
        • Examples:
          • Ag+ = silver ion
          • Fe2+ = iron(II) ion, or ferrous ion
        • Other Examples:
          • Ag+, Al3+, Ba2+, Bi3+, Br–, Ca2+, Co2+, Co3+, Cr2+, Cr3+, Cs+, Cu+, Cu2+, Fe2+, Fe3+, H+, Hg2+, Hg22+, K+, Li+, Mg2+, Mn2+, Mn4+, Na+, Ni2+, Pb2+, Pb4+, Rb+, Sn2+, Sn4+, Sr2+, Zn2+
        • Worksheet: Study Aid B
    • -the first element in a nonmetal/nonmetal binary compound (sometimes used with a prefix if more than one of that element exists in the compound)
      • Examples:
        • CBr4 = carbon tetrabromide
        • TeO3 = tellurium trioxide
        • S2F6 = disulfur hexafluoride
      • Other Examples:
        • CBr4, CCl4, Cl2O7, ClO2, CO, CO2, ICl, N2O, N2O4, N2O5, P2O3, P2S5, P4O10, PBr5, PCl3, S2F6, SeO2, SF6, SiS2, SO2, SO3, TeO3
