TERMINOLOGY AND SYMBOLISM OF THE ATOMIC THEORY
The problem of terminology and symbolism in chemistry in connection with globalization processes, adoption in Russia the Bolognian declaration, use of test systems in education for study and check is discussed in the paper. The analysis of terms, symbols and definitions (atom, molecule, formula unit, equivalent, chemical reaction and other), which are the content of atomic theory and stoichiometry is carried out. The tautology of the classical definition of atom and the need of using the definition, based on atom characteristics and structure, are shown. The need of keeping to the classical definition of molecule as a particle, which is a carrier of substance chemical properties and separation of formula and formula unit definitions are shown. The mole of substance definition is discussed in the context of its use in the chemical texts. The sequential system of statements and symbols related to the equivalents of chemical elements and chemical compounds is proposed. Stoichiometric valence of an inorganic substance, equal to the equivalent number in a certain reaction is proposed to consider the property of the substance.
