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 ...

As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves. The positive areas of the water molecules surround the negative Chloride ions.

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.
