Quiz on Sodium element

Sodium is a soft, silvery-white metal with the atomic number 11 and the symbol Na. It belongs to the alkali metal group in the periodic table and is highly reactive, especially with water, producing hydrogen gas and heat. Sodium is never found in its pure form in nature due to its reactivity; instead, it occurs in compounds such as table salt (sodium chloride). Sodium plays a crucial role in the human body by helping maintain fluid balance and transmitting nerve impulses. Industrially, it is used in the manufacture of glass, soap, and various chemicals.
