main group elements and heteroatoms, scope - electronic configuration of atom, and aufbau principleformal logic-I, oxidation number and formal charge - number of charges in atom, of simple substance, ion or moleculeheteroatoms, elements of groups 15, 16 and 17 - unshared electron pair(s), ...
The main group elements can be found in groups 1, 2, and 13 through 18 on the periodic table. These are the first and second columns at the left of the table, and the final six columns on the right. Which elements are main group metals? The main group metals can be found in groups...
The formation of the dimeric composition, [(MeSn(O)O2CC6H11)2(MeSn(O2CC6H11)3]2, appears to be an intermediate hydrolysis product on the way to the drum composition. The X-ray structure reveals an unfolded drum array. The distannoxane unit which is represented as the sides of the ...
In (L nM) 2X-Hal compounds which contain a trigonally planar coordinated bridging element (X = P, As, Sb) stabilized by two 16-electron L nM fragments the halogen may be substituted by monovalent organometallic groups. In the resulting m... Gottfried Huttner,Ute Weber,Beate Sigwarth,......
The chemistry of various groups of elements is then discussed. The book incorporates a valuable chapter on inorganic polymers, discussing the chemistry of materials such as silicates, silicones, phosphazenes and diamond. Additional material is available on the website at www.rsc.org/tct Ideal for ...
Clusters of the Heavier Elements of Main Groups 14-16: A Novel Synthetic Route for Polyanions in Molten Crown EtherA novel procedure allows the synthesis of homoatomic polyanions directly from the elements E (E = Sn, As, Sb, Te) in molten A/18-crown-6 as reaction medium (A = K, Rb...
Despite the wealth of established transition-metal multicarbonyl complexes, no elements outside groups 4 to 12 of the periodic table have yet been shown to react directly with two or more CO units to form stable multicarbonyl adducts. Here we present the synthesis of a borylene dicarbonyl ...

market and consequently means higher prices for consumers. However, sometimes government regulation is needed to protect consumers and the common good, two areas where the profit motives of capitalism might be in conflict with crucial elements of society such as the environment and banking regulation....
