In a Lewis structure, these six dots are arranged so that an atom has two lone pairs and two single electrons. The ore concentrates are mostly sulfidic; they are converted to the oxides by heating under air in a process known as roasting: Some of the germanium is left in the dust produced, while the rest is converted to germanates, which are then leached (together with zinc) from the cinder by sulfuric acid. In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. Australia's Top Business Stories . Starkville Daily News National Championship.
