  1. Hello. This is my presentation for the chemistry element project.
  2. Okay. I chose the elements silicon.
  3. Its chemical symbol is s I.
  4. The atomic number is 14 and its atomic masses 28.85
  5. atomic messages.
  6. The number of products nutrients in elections is 14.
  7. Okay, The physical properties or the following.
  8. Its original state is solid with a great color silicon
  9. with shiny metallic luster.
  10. It is very brittle and it is not malleable or
  11. ductal. The density is 2.3296 g per cubic centimeters.
  12. Its melting point is 1000 414 degrees Celsius and its
  13. boiling point is 3265 degrees Celsius.
  14. Theo Element silicon was discovered by a chemist named Johns
  15. Jacobo Chile's.
  16. He discovered the element in 18 24 in Sweden.
  17. Silicon is one of the most useful elements to exist.
  18. It is used in the making of breaks, glass and
  19. ceramics. Silicon is also used as a component of still
  20. in a systemic conductor to create solar cells.
  21. Transistors in microchips.
  22. Since silicon is used in things that are all around
  23. us, we can most likely find silicon even in our
  24. own homes.
  25. Silicon is used to make silicon, which produced silicone oils
  26. that are used for cosmetics and hair conditioners.
  27. Phones with your part of our everyday life also contains
  28. silicon as well as keyboards and specialists.
  29. These are just some examples of products that contain silicon,
  30. such as makeup, shampoos, phone cases and solar panels.
  31. Yeah, China is the world's leading producer of silicon.
  32. It is followed by Russia, Norway in the United States,
  33. though it is producing many more countries as well.
  34. Silicon is now found us a free element in nature.
  35. It mostly it is mostly found in silicon minerals, which
  36. make about 90% of the earth's crust.
  37. There is a graph showing the top countries in silicon
  38. production from 2014 to 2019, and also right now there
  39. is no evidence that shows theologian Mint is harmful to
  40. the environment.
  41. Some interesting facts about silicon is that it is actually
  42. the second most abundant element in Earth's crust, and it
  43. is the eighth most abundant in the universe.
  44. Silicon has a unique property in which it expands when
  45. it freezes similar to water.
  46. It plays a major role in the life of plants
  47. and animals, and it is necessary for the making of
  48. electron ICS and buildings be.
  49. And then these are just my citations of the roast
  50. resources that I used.
  51. Okay? Yeah.
  52. And lastly, this video shows the phone case that I
  53. tried my best to make, and it is made using
  54. Harkless Fix that contain silicone, which is made of the
  55. elements silicon.
