Why is silicon so abundant on earth?
The reason why silicon is the most common element within the rocky planets, is because it was the most common element (next to hydrogen) in the original nebula that condensed to form the Solar System. Perhaps other planetary systems around other stars may have more aluminum or iron than silicon.

What is a fun fact about silicon?
Interesting Silicon Facts: It is the eighth most abundant element in the universe by weight. It is almost never found as a pure free element naturally. Silicon makes up slightly more than 27% of the Earth’s crust. Over 90% of the crust is made of silicate-containing minerals and compounds.
Where did silicon come from in the universe?
Most of the silicon used in electronic devices comes from silica. In total, silica makes up about 60 percent of Earth’s crust. Its widespread presence on Earth is no surprise, as silica dust has been found throughout the universe and in meteorites that predate our solar system.
How did silicon get its name?
The name silicon derives from the Latin silex or silicis, meaning “flint” or “hard stone.” Amorphous elemental silicon was first isolated and described as an element in 1824 by Jöns Jacob Berzelius, a Swedish chemist. Impure silicon had already been obtained in 1811.
Who discovered silicon and when?
Silicon was first isolated in the laboratory of Swedish chemist Jöns Jacob Berzelius in 1824. Berzelius extracted his sample by heating potassium in an earthenware vessel until the silicate rock began to break down. When he rinsed away the impurities, Berzelius was left with a sample of almost pure silicon.
What are some interesting facts about Silicon?
– Oxygen (47.3%) and silicon (27.7%) together make up 75% of the weight of Earth’s crust. Most of the crust’s silicon exists as silicon dioxide; we are familiar with this as sand or quartz. Silicon is the second most abundant element in our planet’s crust.[1] – Silicon is the seventh most abundant element in the universe and is classified as a metalloid. Its atomic symbol is Si, and its atomic number is 14.[2] – About 25 percent of the Earth’s crust is silicon; weirder spots where this element appears include menstrual cups, breast implants and oven mitts. Silicon is the seventh-most abundant element in the universe and the second-most abundant element on the planet, after oxygen, according to the Royal Society of Chemistry.[3]
Where does silicon come from?
The name silicon comes from the Latin word silicis which means flint. Where the silicon junctions come to the surface of the silicon is a very sensitive area, which we used to expose and had to work awfully hard to keep clean.
Why was silicon named?
Silicon was first discovered by Jons Jacob Berzelius in 1824, and is named after the Latin word for flint, “silex.”. It was named this because flint is one of the common forms of silica. It was discovered after heating potassium chips in a container made of silica, an extremely common compound of one silicon atom bonded to two oxygen atoms.
