Sodium and chlorine combine to form sodium chloride (chemical formula NaCl), which is commonly known as Common Salt and is an essential food ingredient in many cuisines. Sodium is a metal and readily donates an electrons to become positively charged sodium ion (Na+). Chlorine is a very electronegative non-metal and readily accepts electrons to become a negatively charged chloride ion (Cl-). These anions and cations bond with each other in an ionic bond to form sodium chloride. Apart form its major application in food, it is also commonly used for de-icing the roads in cold regions. It also serves as the main source of sodium and chlorine. Salt water is our biggest source of sodium chloride and that is where we get common salt from.
Hope this helps.
