Some foods, including ready-to-eat foods such as items from the deli or bakery, are not required to have nutrition labels.

In chemical terms, salts are ionic compounds. To most people, salt refers to table salt, which is sodium chloride. Sodium chloride forms from the ionic bonding of sodium ions and chloride ions. The element sodium is very reactive and can even react explosively with water. For this reason, it is not found free in nature. Sodium, located at the far left of the third row of the periodic table, has only one valence electron.
Because its nucleus has a relatively small effective positive charge, it readily loses this outer electron. In contrast, chlorine, at the other end of the same row of the periodic table, has built up six additional protons and so has a great affinity for electrons and can readily accept one more in its valence shell of electrons.
