In T_EX , a computerized type setting system, the T_EX macro commands were made and defined in order to print out any symbols that might be needed in chemistry. When a document has to be made by T_EX , the pictograms, such as structural formulas for chemical compounds, tools for chemical experiments and so on , the periodic tables, Bohr's models of hydrogenlike atoms and hazardous labels for chemical compounds, are able to be inserted easily in the document by these T_EX commands.
