The geometrical structures of halides and oxides of elements from the fourth group of the periodic tabledoi:10.1007/BF00744248O. P. CharkinM. E. DyatkinaPleiades Publishing LtdJournal of Structural Chemistry
Halides of molybdenum, niobium, tantalum, titanium, tungsten, uranium, vanadium, zirconium and hafnium having a valency lower than that corresponding to their Group in the periodic table are produced by reacting a halide of higher valency with a carbide of one of said metals in the form of par...

Provides comprehensive data for each element of the periodic table of elements including up to 40 properties, names in 10 languages and common chemical compounds. Information also provided for 3,600 nuclides and 4,400 nuclide decay modes.Editor...
5c). Furthermore, in the intensity profiles, the peak position of each atom is very periodic, and there was no variation in the peak intensity. It follows that all the constituent atoms in our Cs2AgBiBr6 single crystals are highly ordered at the atomic level, resulting in the well-defined...
Trends in Nuc. Strength • Of a conjugate acid-base pair, the base is stronger: OH - > H 2 O, NH 2 - > NH 3 • Decreases left to right on Periodic Table. More electronegative atoms less likely to form new bond: OH ...
Catalytic dehalogenation (or hydrodehalogenation) of halogen- containing compounds of elements of group IV of the periodic table in the presence of hydrogen is carried out using a finely-dispersed catalytically active material which comp... G Roewer,U Paetzold,H Walter - US 被引量: 53发表: 1998...
and alkylcycloalkyl. I prefer the alkyl radicals in general, and more preferably those in which the alkyl has up to about 10 carbon atoms per R group. M is a metal of Group IIA of the Periodic Table with an atomic number of at least 12 and is magnesium, calcium, strontium, or barium...
