A two-dimensional model for the ionic lattice in sodium chloride Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 ...

This paper presents a new technique for estimation of lattice energies of inorganic ionic compounds using a simple formula. This new method demonstrates the relationship between chemical hardness and ...

Could a new periodic table be on the horizon, populated not by conventional elements but by new ‘superatoms’ designed in the lab? This is the intriguing implication of new work by US chemists, who ...

r_0 = Sum of ionic radii (nm) n = A constant typically around 7-12 This equation can provide reasonably accurate results for simple ionic compounds, but its accuracy decreases for more complex ...

Regioselective mononitration of simple aromatic compounds has been investigated in several different air- and moisture-stable ionic liquids. Use of a mixture of nitric acid and acetic anhydride as the ...
