Chemical element "Sb" (stibium) for antimony. Chemical symbols are understood internationally when element names might require translation. There have sometimes been differences in the past. For example, Germans in the past have used "J" (for the alternate name Jod) for iodine, but now use "I" and "Iod". The first letter of a chemical symbol is always capitalized, as in the preceding examples, and the subsequent letters, if any, are always lower case (small letters). Thus, the symbols for californium and einsteinium are Cf and Es. There are also symbols in chemical equations for groups of chemical elements, for example in comparative formulas.
Systematic element name for 4). There are two elision rules designed to prevent odd-looking names. The suffix "-ium" overrides traditional chemical suffix rules; thus elements 117 and 118 were "ununseptium" and "ununoctium", not "ununseptine" and "ununocton". This does not apply to the final trivial names these elements receive once confirmed; thus element 117 and 118 are now "tennessine" and "oganesson". For these trivial names, all elements receive the suffix "-ium", except those in group 17 which receive "-ine" (like the halogens) and those in group 18 which receive "-on" (like the noble gases). The systematic symbol is formed by taking the first letter
