natriy
Natriy is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white alkali metal. Sodium is highly reactive, easily losing its single outermost electron to form a positively charged ion. This property makes it a strong reducing agent. Sodium is essential for life and is a major component of the extracellular fluid in many organisms, including humans. It is also used in various industrial applications, such as in the production of sodium vapor lamps and as a coolant in nuclear reactors. Sodium is abundant in the Earth's crust and is the sixth most abundant element overall. It is typically found in compounds, such as sodium chloride (table salt), and is extracted through various chemical processes. Sodium has several isotopes, with the most stable being sodium-23. The element was first isolated by Sir Humphry Davy in 1807 through the electrolysis of sodium hydroxide.
