WebIons are atoms or groups of atoms that gain an electrical charge by losing or acquiring electrons. For example, in the reaction that forms salt from sodium and chlorine, each sodium atom donates an electron, which is negatively charged, to a chlorine atom. The result is sodium chloride (NaCl), composed of one positively charged sodium ion (Na+) … WebIt is also the fifth most abundant dissolved ion in seawater. Calcium was named after the Latin term calx meaning lime, and is a reactive silvery metallic element found in Group 2 of the periodic table. It was first isolated in 1808 in England when Sir Humphry Davy electrolyzed a mixture of lime and mercuric oxide.
