Chapter Overview
Chapter 5, 'Group 2 Elements', discusses the general trends in physical properties and chemical reactivity of alkaline earth metals. It covers trends in ionization energy, chemical reactivity, atomic radius, and melting point down the group.
The chapter details chemical reactions of Group 2 elements with oxygen, water, and dilute acids, alongside the reactions of their basic oxides with acids. It also contrasts their reactivity with Group 1 elements, lists their industrial, agricultural, and medical uses, and details the thermal decomposition of their carbonates and nitrates.
Additionally, students will examine solubility trends of Group 2 hydroxides and sulfates, analyzed through hydration enthalpy and lattice energy variations. The chapter concludes with complexes of alkaline earth metals and extraction/purification processes such as the electrolysis of beryllium and magnesium.
