None of the carbonates is anything more than very sparingly soluble. Ions of both form complexes such as BeF42-, AlF63- etc. Superoxides are either yellow or orange in color and paramagnetic in nature. The hydroxides of alkaline earth metals therefore come under weak base category. On decomposition, lithium nitrate gives lithium oxide. alkali and alkaline earth metals respectively. The carbonates of alkaline earth metals can be regarded as salts of weak carbonic acid (H2CO3) and metal hydroxide, M (OH)2. In manufacturing of glass, soap, borax and caustic soda. The carbonates become less soluble down the group. In Wolff‐Kishner reduction, the carbonyl group of aldehydes and ketones is converted into. Note – M can be any alkaline earth metal. Note – Li is a small size alkali metal with very high hydration energy, so it reacts less vigorously with water. Hydroxides of all other alkaline earth metals are basic in nature. Aluminium and beryllium both do not attack acids easily. Calcium plays a vital role in blood coagulation, neuromuscular function and building of cell walls in plant cells.

M+(dissolved in ammonia) + e- + NH3 MNH2 + 1/2H2. Potassium ions activate many enzymes which help in production of energy by oxidation of glucose. Lithium shows diagonal relationship with magnesium. They are important minerals of our body. Nitrates of alkaline earth metals are formed by dissolution of the carbonates in dil. The term "thermal decomposition" describes splitting up a compound by heating it. Only Be and Mg react with N2 directly. ), Decreases on moving from top to bottom in the group (Mg has exceptionally low and Ba has exceptionally high b.p.). Chlorides of both are deliquescent but their hydrates (LiCl.2H2O and MgCl2.8H2O) are crystalline solids. This is due to, Three centre - two electron bond is present in. (a) Nitrates (b) Carbonates (c) Sulphates Answer: (a) Nitrates of both group 1 and group 2 elements are soluble in water because hydration energy is more than the lattice energy. They follow the following trend – F- > Cl- > Br- > I-. Beryllium sulphate is readily soluble in water.

There is little data for beryllium carbonate, but as it reacts with water, the trend is obscured. Used in the production of paper, artificial silk and various chemicals. Beryllium hydroxide is amphoteric in nature which means it reacts with acid and base both. Sodium and potassium ions differ in their concentrations in the cell fluid and also differ quantitatively in their ability to penetrate the cell membrane. Aqueous solution of their oxides and hydroxides turn red litmus paper into blue. The elements of group 1 are known as alkali metals because their oxides and hydroxides are basic in nature. In general, the most common main group elements used as carbonates are the Alkali and Alkaline metals.
