In this monograph, group-theoretical approaches are used to building the system of hadrons and to describe qualitatively the properties of chemical compounds. This serves as a complement to numerically and approximately solving the many-electron Schrdinger equation to understand the behaviour of ...
The name indicates the mass of an atom, expressed in atomic mass units (amu). Most of the mass of an atom is concentrated in the protons and neutrons contained in the nucleus. Each proton or neutron weighs about 1 amu, and thus the atomic mass in always very close to themass (or nucl...
its compounds,a and b are fitting constants,n is the periodic ordinal number,has been suggested in this paper:The formula can be used in calculating twenty quantitives or more of the element and its compounds in the same group of the element periodic table,and better result.can be obtained...

The reactions of triphenylgermane and triphenyltin hydride with coordinatively saturated organozinc or organocadmium compounds give organometallic complexes containing Group IV (Ge, Sn)-Group II(Zn, Cd) metal metal bonds. The 2,2′-bipyridine complexes show solvent-dependent charge-transfer absorptions...
