TY - GEN AU - Fet, Abram I. TI - Group theory of chemical elements: structure and properties of elements and compounds SN - 9783110475180 U1 - 530.12 PY - 2016/// CY - Berlin PB - De Gruyter KW - Symmetry KW - Quantum systems KW - Chemical elements KW - Group theory N2 - In this monograph, group-theoretical approaches are used to build a system of hadrons and qualitatively describe the properties of chemical compounds. This serves as a complement to numerically and approximately solve the many-electron Schrödinger equation, in order to understand the behavior of chemical elements. Besides general theory, specific results are compared with experimentally measured chemical properties ER -
