Atmospheric evolution in the Precambrian: Constraints from water
... The effects of Po2 on mineral dissolution have been studied for Fe(II)-bearing silicate minerals (Murakami et al., 2004; Sugimori et al., 2009, 2012). Although the observation of redox-insensitive elements (e.g., Mg and Si) released during dissolution of the minerals has revealed that dissolution ra ...

Chemical Bonding and Molecular Geometry
... In ionic compounds, electrons are transferred between atoms of different elements to form ions. But this is not the only way that compounds can be formed. Atoms can also make chemical bonds by sharing electrons equally between each other. Such bonds are called covalent bonds. Covalent bonds are form ...

Coordination Numbers and Structures
... In 1893, Werner was the first to propose correct structures for coordination compounds containing complex ions, in which a central transition metal atom is surrounded by neutral or anionic ligands. For example, it was known that cobalt forms a "complex" with formula CoCl3•6NH3, but the nature of the ...
