11.3 Group II Oxides, Hydroxides and Carbonates Group II oxides All Group II oxides(except beryllium oxide) reacts with water, at least to some extent to give the corresponding hydroxides Beryllium oxide is insoluble because Be²⁺ ion is a very small and highly charged...
11.4 Thermal Decomposition Thermal decomposition of Group II salts In general, compounds with high charge density cation and large anion size tend to decompose more easily(less stable on heat) due to the greater polarisation of anion by the cation. Thermal...
11.5 Uses of Group II Compounds 11.1 of Group II Compounds Some ceramics contain magnesium oxide, MgO and they can be used as: electrical insulators in industrial electrical cables a refractory in furnace linings because it has a high melting (However, it...
11.2 Reactions of Group II Elements Reaction with oxygen gas, O2 All Group II elements(except beryllium) burn in oxygen with a bright flame to form monoxides 2M(s) + O2(g) → 2MO(s) ; where M = A Group II element 2Mg(s) + O2(g) → 2MgO(s) ; burns with brilliant...
11.1 Physical Properties of Group II Elements Introduction to Group II elements Group II elements(also called the 'alkaline earth metals') are s-block elements with a characteristic outer shell configuration ns². Group II elements are very reactive metals. They...
CHAPTER 11: Group II Physical Properties of Group II Elements Reactions of Group II Elements Group II Oxides, Hydroxides and Carbonates Thermal Decomposition Uses of Group II Compounds Learning outcomes: describe the reactions of the elements with oxygen, water and...
