152 Graphite oxide can be used as a catalyst in the synthesis of imines and their derivatives. As of, prices for small samples (up to 100 g) of silicon, antimony and tellurium, and graphite, aluminium and selenium, average around one third the cost of silver (US1.5 per gram or about 45 an ounce). 488 The chemistry of astatine in aqueous solution is mainly characterised by the formation of various anionic species. 299 Apseloff 1999 Trivedi, Yung Katz 2013,. . 1, Clarendon, Oxford Siebring BR 1967, Chemistry, MacMillan, New York Siekierski S Burgess J 2002, Concise Chemistry of the Elements, Horwood, Chichester, isbn Silberberg MS 2006, Chemistry: The Molecular Nature of Matter and Change, 4th., McGraw-Hill, New York, isbn Simple Memory Art. 9235, doi :.1021/ed075p923 Gillespie RJ Robinson EA 1963, 'The Sulphuric Acid Solvent System.

This applies to their most thermodynamically stable forms under ambient conditions: carbon as graphite; phosphorus as black phosphorus; n 53 and selenium as grey selenium. Indeed, the boundary of a class is rarely sharp." The lack of a standard division of the elements into metals, metalloids, and nonmetals is not necessarily an issue.

Tellurium reacts with boiling water, or when freshly precipitated even at 50 C, to give the dioxide and hydrogen: Te 2 H2O TeO2. 356 Compared to phosphorus, the stronger metallic character of arsenic is indicated by the formation of oxoacid salts such as AsPO4, As2(SO4)3 n 37 and arsenic acetate As(CH3COO)3. 76 ; Mann.
