SODIUM SYMBOL PERIODIC TABLE: Everything You Need to Know
sodium symbol periodic table is a fundamental concept in chemistry and physics, and understanding its significance can be a valuable asset for students, researchers, and professionals alike. In this comprehensive guide, we will delve into the world of sodium's periodic table symbol, its history, properties, and practical applications.
What is the Sodium Symbol in the Periodic Table?
The sodium symbol, represented by the letter "Na", is the chemical element with the atomic number 11 and the atomic mass of 22.98 u. It is an alkali metal that belongs to the first group of the periodic table, also known as the Group 1 elements.
Na is a highly reactive metal that readily loses one electron to form a positive ion, known as a sodium ion. This reactivity is due to its single valence electron, which makes it a highly electropositive element.
History of Sodium in the Periodic Table
The discovery of sodium dates back to the early 17th century when the English chemist Humphry Davy isolated it from caustic soda in 1807. The name "sodium" comes from the Arabic word "al-sawia", meaning "plant", as it was first extracted from the ash of plants.
