Abstract
The article is a discussion and analysis of research related to the development of a theoretical model for the determination of physical properties of metals, as well as common semimetals and non-metals occurring in the form of a solid under normal conditions. This is the basis for further consideration in this direction because the presented discourse is limited to the analysis of pure elements. The innovation of the presented approach is an attempt to use only information on the physical atomic structure of elements in relation to their physical properties. The article attempts to link one of the basic physical properties that are the density of metal with its atomic structure. The study involved 75 different chemical elements. The theoretical calculation results determined by means of the presented model remain in correlation with experimental values for 61 chemical elements, not exceeding the calculation error of 6%. This can be considered a satisfactory result of the model in comparison with other models, for example, to determine viscosity, whose differences in computational results, often very much different from experimental values, as well as were directed to a narrow group of materials tested. In addition, other models are often semi-empirical, where in comparison with the theoretical model based only on the atomic structure puts it in a very interesting light.
