Introduction
Hi! My name is Marco and this PowerPoint is made for my science project! 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!

4. Basic Information Periodic Table Symbol: Na Element Number: 11
Element Type: Alkali Metal
Melting Point: 97.72 °C
Boiling Point: 883 °C
Atomic Weight: g/mol
Density: 0.971g/cc
Atomic Volume: 23.7cc/mol

5. Etymology
The word ‘Sodium’ comes from Medieval Latin “Sodanum” which means headache medicine
Soda also comes from “Sodanum” since soda contains Sodium
Its Periodic Symbol, Na, comes from the Latin word “Natrium” or Arabic “Natrun”

6. Appearance Bright; Reflective Silver in Color Soft Surface
Waxy Metallic Texture

7. Discovery
Sodium 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. Usages
Sodium is used in multiple ways. Ways it is used as an element include:
Maintaining proper nerve and muscle function
Purify melted metals
Improves structures of other compounds
Used in glass, soap, paper, textile, chemical, petroleum, and in most metal objects
Sodium 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…adder
Sodium Peroxide is used to whiten wood to make paper; and used in scuba gears and submarines
Sodium 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 stars
2.36% of the Earth’s crust contains sodium
Found 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 element
Available in animals to maintain proper muscle and nerve function
Fizzes then explodes when exposed to water, snow, ice, etc.
Sodium can shred the surface of other metals

11. Contact With H2O
Now 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 Facts
Sodium is the 6th most common element in the Earth’s crust
Sodium, 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. Conclusion
In 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.
