What Is the Difference Between Sodium and Salt?

Sodium is a chemical element.It is very reactive, so it isn''t found free in nature. In fact, it undergoes spontaneous coustion in water, so while sodium is essential for human nutrition, you wouldn''t want to eat pure sodium. When you ingest salt, the sodium, and the chlorine ions in sodium chloride separate from each other, making the sodium available for your body to use.
