Salt, commonly known as table salt, is primarily composed of sodium chloride (NaCl).

Here's a breakdown:

* Sodium (Na): A silvery-white, soft, highly reactive metal.

* Chlorine (Cl): A pale green, poisonous gas.

When sodium and chlorine react chemically, they form an ionic compound called sodium chloride. This compound is what we know as salt.

Additional information:

* While sodium chloride is the main component of table salt, it may also contain small amounts of other minerals, such as iodine, potassium, magnesium, and calcium.

* Sea salt, mined salt, and rock salt can have different mineral compositions.

* Salt is essential for human health and plays a vital role in regulating fluid balance, nerve impulses, and muscle contractions.
