Slide 2 By Rachel WebElements Periodic Table of the Elements Slide 3 Physical Properties of Sodium Sodium is a silvery-white color. Sodium is attracted to magnetic fields. Sodium is soft enough to be cut with a knife. Sodium is a solid. Sodium conducts electricity. Sodium is metallic. Slide 4 Crystalline Structure of Sodium Sodium has a body-centered cubic crystal structure. Slide 5 Sodium Facts Symbol: Na Atomic number: 11 Atomic weight: 22.99 Number of protons: 11 Electrons: 11 Neutrons: 12 Slide 6 More Sodium Facts Sodium is in the s-block in the periodic table. Its in period 3 in the periodic table. Sodium is in Group 1: Alkali metal. The electron configuration of sodium is 1s 2 2s 2 2p 6 3s 1. Slide 7 Uses of Sodium Sodium compounds are used in the following industries: Paper industries Glass industries Soap industries Textile industries Petroleum chemical industries Metal industries Rubber industries Slide 8 More Uses of Sodium Sodium hydroxide gets grease out of the drains. Sodium hydroxide is also needed for liquid soap. Sodium is in yellow highway lights. Sodium is used in baking soda. Sodium is also used in table salt. Sodium is used in antibiotics, rat poison, and in ceramics. Slide 9 Where is Sodium Found? Sodium is found in the core of massive stars, where it is the product of the fusion of carbon. Most sodium on earth is found in the crust where it is found in compounds. Sodium is too reactive to be found free in nature. Sodium makes up about 2.6% of the earths crust, making it the sixth most abundant element on earth. Sodium is the most abundant of the alkali metals. Slide 10 Sodium Facts Sodium reacts with ammonia, hydrogen, halogens, and alcohol. Sodium reacts with water at room temperature and forms into a sphere if the piece of sodium is large enough. The oxidation states of sodium is +1. Slide 11 Sodium Sodium acts to maintain the normal hydration state of the bodily fluids. Sodium was isolated in 1807 by Sir Humphrey Davy.
