Metals and Nonmetals - Chemistry | Socratic

Gold, silver, aluminum, iron, and copper are malleable. Non-malleable metals such as tin will break apart when struck by a hammer. A metal behaves as an array of metal ions or kernels immersed in a “sea” of mobile valence electrons. Metallic bonds consist of the attractions of the ions to …

IUCr scripts server - Activity inhibition and crystal …

Like most phosphate-processing enzymes, it requires a divalent metal ion such as Mg2+ (or Mn2+) as a cofactor to alyse nucleotide-cleavage and nucleotide-transfer reactions. On the other hand, calcium (Ca2+) inhibits this enzymatic activity, in spite of the fact that Mg2+ and Ca2+ present comparable binding affinities and biological availabilities.
