SILICON

SILICON

1) My name is Silicon in German I am Silicium, in Italian I am Silicio, and in Swedish I am Kisel.
I was discovered by Jöns Jacob Berzelius in Sweden and my name means "flint".

2) I look metallic, and my lust is very shiny and I look purely like the color silver.

3) My most common isotope has 14 protons and usually around 14 neutrons. My naturally occuring isotopes are 28-Si, 29-Si, and 30-Si, my half life is 170 years, and my natural abundancy for 28-Si is 92.2297%, for 29-Si is 4.6832%, and for 30-Si is 3.0872%. My average atomic mass is 28.0855.

4) My neutral atom has 14 electrons and 3 shells of electrons.

5) My atomic radius is 110pm.

6) The properties of my pure elements form include a melting point of 1414 Celcius, a boiling point of 2900 Celcius, a hardness of 6.5, shiny-silver lust, conductive and I react with Oxygen, the Halogens, and bases.

7) The abundance of Silicon in Jerry Dudum's body, who weighs 140lbs, is 36.4g. My abundancy in the Earth's crust is 270000000 ppb by weight and in our Universe is 700000 ppb by weight.

8) I form the compounds Silane SiH4 and Silicon Oxide SiO2 but I can form many, many more compunds these are just two of them.
9) I was discovered by Jöns Jacob Berzelius in Sweden, I was discovered when they were heating potassium chips in a silica container and then washing away the residual by-products.
10) Silicon is used in many things but two very common ones are it is used in making computer chips and making and producing glass which is used in a variety of ways.
11) Silicon is the most abundant element in the Universe.
