Facts You Should Know: The Periodic Table Quiz The high electrical and thermal conductivities of the simple metals (i.e., the non-transition metals of the periodic table) are best explained by reference to the free-electron theory. According to this concept, the individual atoms in such metals...
Current research efforts on single-atom catalysts (SACs) exclusively focus on nonmetal or transition-metal atoms as active centers, while employing main-group metal elements is seemingly excluded because their delocalized s/p-bands are prone to yield a broadened resonance for the interaction with adso...
The crystal of a nitride of a Group-13 metal on the periodic table according to the present invention contains oxygen atoms and hydrogen atoms and has a ratio of the oxygen concentration to the hydrogen concentration of 0.5 to 4.5.MIKAWA Yutaka...
the integers of which are equal to the positive electrical charges of theatomic nucleiexpressed in electronic units. In subsequent years great progress was made in explaining the periodic law in terms of theelectronic structureof atoms and molecules. This clarification has increased the value of the...
Finally, biomimetic structure of chitosan soaked in TiO2 precursor solution, and TiO2 is successfully grafted on the surface of chitosan due to hydrogen bonds formed by the hydroxyl and amino groups on the surface of chitosan and the oxygen atoms in TiO2. This bionic structure not only endows ...
In recent years, metal nuclearity and coordination effects have been subject to extensive research in this reaction, revealing Au(I)Clx, Pt(II)Clx single atoms and RuOxCly nanoparticles as the active sites of the aforementioned catalysts. On the contrary, the widely recognized key role of the ...
The first two hydrogen atoms tent to bond on two nitrogen atoms, the third hydrogen was prone to bonding at the nitrogen in Cu–N owing to the smaller electron delocalization. Followed by the last hydrogenation step, urea molecule was produced. It can be seen that CuIII-HHTP was more ...
Atomic orbitals of multi-electron atoms To understand the electronconfigurationsof other atoms, it is customary to employ theAufbau(German: “building up”) principle, the basis of which is that, to achieve a multi-electron configuration, the required number of electrons must be added to the orb...
theperiodic tableare explained by the uneven filling of electron shells in the successive rows of the table. Theselectrons may also be promoted toporbitals of the same principalquantum number(within the same shell) by energies similar to those required to formchemical bonds; the lighter atoms are...
