Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions ... and a space filling model (b) of ionic hard spheres. The cohesive energy of NaCl is - 7.90 eV, with a ...

The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near each other. An electron from each atom feels the attraction from the other atom ...

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 ...

Here’s an example using sodium and chlorine ... diagrams for the formation of ions in some ionic compounds – magnesium oxide and calcium chloride.
