It forms when sodium (chemical symbol “Na”) and chloride (“Cl”) ions come together to create white, crystalline cubes. Your body needs salt to function, but too little or too much salt can ...

This two-part activity will help students see the relationship between the arrangement of ions in a model of a sodium chloride crystal and the cubic shape of real sodium chloride crystals. Question to ...

Small square salt crystals are visible on the bottom of the container. What do you think happened to make the dissolved salt form into crystals again? The water evaporated and the sodium and chloride ...

Bouncing X-rays off the crystals showed the scientists that they had created two new hydrates. One had a crystal structure of two sodium chloride molecules for every 17 water molecules.

This salt crystal is both exotic and common: It’s actually table salt — also known as sodium chloride, with the chemical formula NaCl — but bound up with water molecules to form a hydrate ...

The sodium chloride crystals, which only could have formed in the presence of water, were discovered in the sample of asteroid Itokawa that was returned to Earth by Japan's Hayabusa mission back ...
