There are 12 sodium ions on the edges and one in the centre of the unit cell. Each sodium ion present on the edge contributes one fourth to the unit cell and sodium ion present at body centre contributes one to the unit cell.

The ions present in NaCl is one ion of Na and one ion of Cl.

six chloride ions

-In the lattice structure of NaCl there are 13 octahedral voids (12 edge centres + 1 body centre) and Chloride ions occupies corners and centres of each face of the cube thus there are 14 chloride ions in each unit cell. Thus, in each unit cell of NaCl there are 14 chloride ions and 13 sodium ions.

A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. There are three different types of unit cells in the cubic crystal system.

Because of this, each sodium ion, is surrounded by six chlorine ions, and each chlorine ion is surrounded by six sodium ions. A crystal builds up like this, giving the sodium chloride crystal a cubic structure. This cubic structure is reflected in the cubic shape of salt crystals.

When the NaCl is doped with Sr+2 ,it forms solid solution. Few Na+1 gets replaced by few Sr+2. Hence the doping i.e adding of impurities of SrCl2 changes the structure of NaCl. thanks!

Rock salt also known as NaCl is an ionic compound. It occurs naturally as white cubic crystals. The structure of NaCl is formed by repeating the unit cell. It has an organized structure and has a 1:1 ratio of Na:Cl.

It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpetre (or saltpeter in North America)….Potassium nitrate.
