Table salt component refers to the chemical element CHLORINE, which is an essential part of table salt. CHLORINE is a halogen element and is represented by the symbol Cl on the periodic table. It is a yellow-green gas at room temperature and is highly reactive. CHLORINE is used in many industrial processes, such as water purification, and is also found in many household products, including bleach and some swimming pool chemicals. Table salt is composed of two elements, sodium and CHLORINE, and when combined, they form sodium chloride, or table salt.
