If you were to look at grains of table salt (sodium chloride, NaCl) with a magnifying glass, you would see that each grain is a little cube. Why are salt grains cubical?
All extended structure compounds form cubes.
Sodium and chlorine atoms both have cubical shapes.
In the extended structure of NaCl, atoms are arranged in a cubical pattern.
A molecule of NaCl contains eight atoms, each at one of the corners of a cube.
This is an example of a
