Formulas are the scholar’s Latin of chemistry. Without them, communication across national borders would be unthinkable, and the representation of chemical processes would be as cumbersome as if we had to write our CV in cuneiform [1]. Peter von Zahn [1] highlights the great importance of chemical symbols, characterizing them as a unique means of communication for chemists—regardless of whether they work in Europe or America, in China or Japan. In this sense, it is also a goal of chemistry education to introduce young people to this symbolic language and to enable them to read and understand the achievements of natural sciences and technology in journals and magazines. In particular, models of lattice and molecular structures are used as a basis for understanding chemical symbols and are discussed as abbreviated models for the composition of substances.
