//**__When, how and who discovered it?__**//

Silicon was discovered by Jons Jacob Berzelius in 1824 by [|heating up chips of Potassium in a Silica container]. You produce it by heating sand, clay, and different types of rocks and gems.




 * //__Physical__//**

It's a metalloid (an element that exists as a metal and a solid non-metal), it exists in two different forms of allotropes (two or more physical properties that the element can form). It has a hardness of 7 which means it is a pretty hard element that isn't easy to break.

//__**Chemical**__//

The higher the temperature it is in the more reactive Silicon is. It can not combine with other elements unless it is [|melted], then it can combine with oxygen, nitrogen, ect. Lastly it creates alloys easily - the first two chemical reactions are probably the most common


 * //__Uses__//**

A lot of industries use silicon to make silica which makes cement and other types of brick. A very common thing it is used in is in electronics with transistors with in the electronic.

It is found in many different types of rock in the earths crust. Some ways you can make it is by heating sand or clay in a silica container.
 * //__How It Is Found__//**

__//**Bohr**//__ __**//Model//**__

__//**Unusual**//__ __//**Facts**//__

It is from the Latin word for flint, silex. And the two allotropes are amorphous, and crystalline. Lastly silicon is the most abundant element in the earths crust, taking up about 27.7%. If accidentally breathed in, you can get lung disease called silicosis.
