Natrium is the Latin name for the chemical element sodium (atomic number 11), which is why its chemical symbol is Na. It is a highly reactive, soft, silvery-white alkali metal that plays a crucial role in human health as an electrolyte and in industrial applications, most commonly found as salt (sodium chloride).
