Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

This was a magical moment. The lysozyme structure, composed of 1,000 non-hydrogen atoms, contrasts with the model of sodium chloride composed of just two atoms (shown to the speaker's left in the ...

This helps to visualise the structure. A two-dimensional model for the ionic lattice in sodium chloride A 2D model shows the arrangement of one layer of ions but it does have a major additional ...
