Positive and Negative Ions: ions and Anions - …

Positive and Negative Ions: ions and Anions. ions (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.

silicon | Element, Atom, Properties, Uses, & Facts

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. Crystalline elemental silicon was not prepared until 1854, when it was obtained as a product of electrolysis.
