How did Jacob Berzelius find silicon?
Silicon was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1824 by heating chips of potassium in a silica container and then carefully washing away the residual by-products. Silicon is the seventh most abundant element in the universe and the second most abundant element in the earth’s crust.
What period is silicon found in?
Silicon is the chemical element and it is a member of group 14 and period 3 in the periodic table. Atomic number of silicon is 14 and indicated by symbol Si. It is a metalloid. After oxygen, silicon is the second most abundant element in the Earth’s crust.
What is the origin of silicon?
Silicon (atomic number 14, symbol Si) is a metalloid and a chemical element which is solid at room temperature. It was isolated in 1824 by the Swedish chemist Jons Berzelius who also identified elements such as cerium , thorium, and selenium.
What are important uses of silicon?
Silicon is used to create silicone, which chemically are silicon-oxygen polymers with methyl groups attached. Silicone oil is typically used as a lubricant added to create cosmetics, hair conditioners, and shampoos. Silicone can also be used to create rubber for waterproof sealants in washrooms and windows, pipes and roofs.
What was silicon named after?
Silicon has an melting point of 1687 Kelvin, or 2577 degrees Fahrenheit and a boiling point of 3538 Kelvin, or 5909 degrees Fahrenheit with a density of 2.3290 grams per centimeters cubed. Silicon was discovered in 1823 by Jons Jacob Berzelius . Silicon was named after The Latin word, silex, which means flint.
