It''s Elemental - The Element 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.Today, silicon is produced by heating sand (SiO 2) with carbon to temperatures approaching

Besides their appliion by industry they are appropriate to be used for the validation of special methods used

Metalloid - Wikipedia

13  · A metalloid is a type of chemical element which has properties in between, or that are a mixture of, those of metals and nonmetals.There is neither a standard definition of a metalloid nor complete agreement on the elements appropriately classified as such. Despite the lack of specificity, the term remains in use in the literature of chemistry.. The six commonly recognised metalloids are boron

Chemistry for Kids: Elements - Silicon

Silicon is the second element in the fourteenth column of the period table. It is classified as a meer of the metalloids. Silicon is the eighth most abundant element in the universe and the second most abundant in the Earth''s crust after oxygen. Silicon atoms have 14 electrons and 14 protons with 4 valence electrons in the outer shell.

Atomic Mass of Chemical Elements - Periodic Table

Hydrogen is a chemical element with atomic nuer 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical syol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
