We were asked to pick an element to make a project about, and I picked sodium! I picked sodium because I think it would be interesting to find out more about it and it wouldn’t be so hard since sodium is a pretty common element. Anyway, this is my presentation, and I hope you enjoy!(Click the ‘Home’ button to proceed)
4 Basic Information Periodic Table Symbol: Na Element Number: 11 Element Type: Alkali MetalMelting Point: 97.72 °CBoiling Point: 883 °CAtomic Weight: g/molDensity: 0.971g/ccAtomic Volume: 23.7cc/mol
5 EtymologyThe word ‘Sodium’ comes from Medieval Latin “Sodanum” which means headache medicineSoda also comes from “Sodanum” since soda contains SodiumIts Periodic Symbol, Na, comes from the Latin word “Natrium” or Arabic “Natrun”

7 DiscoverySodium was discovered in 1807 by a chemist/inventor named Humphry Davy. He discovered it in England when he was 29. Sodium wasn’t his only discovery. He also discovered more elements, such as potassium, calcium, magnesium, boron, barium, and lots more!
8 UsagesSodium is used in multiple ways. Ways it is used as an element include:Maintaining proper nerve and muscle functionPurify melted metalsImproves structures of other compoundsUsed in glass, soap, paper, textile, chemical, petroleum, and in most metal objectsSodium is also important when it is “fused” with another element to make a compound! Examples include:Sodium Chloride is used as salt; a food preservative and a taste…adderSodium Peroxide is used to whiten wood to make paper; and used in scuba gears and submarinesSodium Cyanide is used to obtain gold and other metals in mining; and to kill animals
9 Sources Can be found in oceans as Sodium Chloride Common in sun and other stars2.36% of the Earth’s crust contains sodiumFound in many minerals (cryolite, soda niter, zeolite, amphibole, sodalite, etc.)Normally obtained by separating Sodium Chloride (Salt)Found in sweat
10 Effects Towards Environment And Animals Sodium is a highly reactive elementAvailable in animals to maintain proper muscle and nerve functionFizzes then explodes when exposed to water, snow, ice, etc.Sodium can shred the surface of other metals
11 Contact With H2ONow here’s something amazing. I got this video off YouTube of sodium when it comes in contact with H2O/Water. Take a look at it! (You need internet connection for the video to play)
12 Interesting FactsSodium is the 6th most common element in the Earth’s crustSodium, a highly reactive element, when combined with Chlorine, a poisonous element, forms common table salt.The average amount of sodium we consume is a lot higher than what is actually required.Sodium occurs in soap, which is ironic, since soap often comes in contact with water.
13 ConclusionIn conclusion, I would like to say that sodium is, in fact, an interesting element. It makes a breathtaking reaction when exposed to water, and it is HIGHLY reactive. For me, it has been fun researching about this particular element, since we don’t even know how often we come in contact with it when we actually do. I hope you had as much fun watching my PowerPoint as I did making it.
