Chemistry of Sodium Atomic Number and Symbol: The atomic number of sodium is eleven, and its symbol is Na. It is included in the periodic table’s alkali metal group.

Physical characteristics: Sodium is a soft, ductile, silvery-white metal that is very malleable. Its melting and boiling points are 97.79 °C and 883 °C, respectively, which are relatively low.

Reactivity: Sodium hydroxide and hydrogen gas are produced when it reacts vigorously with water. This exothermic process has the potential to explode.

Because of its extreme reactivity, sodium has to be kept submerged in oil to avoid reacting with airborne moisture and oxygen.

Sodium produces a number of compounds, such as:

Sodium chloride, or NaCl, is a common table salt that is used extensively in food preservation and is necessary for human health.
Sodium bicarbonate (NaHCO3), often referred to as baking soda, is a common ingredient in baked goods, an antacid, and a variety of cleaning products.
Na2SO4 (sodium sulphate): Used in the production of detergents and glass.
Biological Role: Sodium plays a key role in a number of biological processes, including the transmission of nerve impulses in living things and the maintenance of fluid equilibrium.
