Question:
All the Group 1A (1) and 2A (2) metals are produced by electrolysis of molten salts. Why?
Transcribed Image Text:
Group 1A (1) Elements (Alkali Metals) > Have valence configuration ¹ > Except for hydrogen, readily lose one electron to form M+ ions in their compounds with nonmetals > React vigorously with water to form M+ and OH-ions and hydrogen gas > Form a series of oxides of the types M₂0 (oxide), M₂O₂ (peroxide), and MO₂ (superoxide) > Not all metals form all types of oxide compounds › Hydrogen forms covalent compounds with nonmetals > With very active metals, hydrogen forms hydrides that contain the H-ion Group 2A (2) Elements (Alkaline Earth Metals) > Have valence configuration ns² > React less violently with water than alkali metals > The heavier alkaline earth metals form nitrides and hydrides > Hard water contains Ca²+ and Mg²+ ions > Form precipitates with soap > Usually removed by ion-exchange resins that replace the Ca²+ and Mg²+ ions with Nat
