Discovery and Uses
Jons Jakob Berzelius discovered the hard, grey element that was silicon in 1824. He did this by heating potassium chips in a silica container, then he washed away all extra residue and repeated the process.

The element silicon has a lot of uses, and it is extremely important because of that. A example of this would be that silicon is the second most abundant element in the earths crust, and this planet might not exist without it. Other uses of silicon are:
1.) Quartz 2.) Flint 3.) The last stage of a heavy star 4.) Silicon chips 5.) Sand 6.) Granite 7.) Ceramics 8.) Your skeleton 9.) Silicone 10.) Medical implants 11.) Enhancing irons magnetic field 12.) Engines 13.)Abrasives 14.) Concrete 15.) Bricks 16.) Precise watches and clocks 17.) Glass 18.) Cookware 19.) Sealants 20.) Adhesives 21.) Insulation |
Interesting facts
1.) Silicon is the eighth most abundant element in the Universe.
2.) Before a heavy star turns Supernova, it is compromised of burning silicon.
3.) You can buy 100g of silicon for $5.4.
4.) Solid silicon does not react with most acids.
5.) Silicon expands when it freezes.
