Alkali metals have low electronegativities. Give solubility order for alkali metal oxides. The carbonates of alkaline earth metals can be regarded as salts of weak carbonic acid (H 2 CO 3) and metal hydroxide, M(OH) 2. All the carbonates of alkaline earth metal are more soluble in the presence of CO 2 due to the formation of corresponding bicarbonates. Doubtnut is better on App. i) Reaction with oxygen and air. For Study plan details. Everything exists as solid as well. (b) high lattice enthalpy. However in this case, for the alkali metal compounds, let's take sodium (because it's the most common) and for the halide compounds, let's take chloride (because it's the most common too). In order of increasing atomic number, the six element names and symbols are: Beryllium (Be) Magnesium (Mg) Calcium (Ca) Strontium (Sr) Barium (Ba) Radium (Ra) If element 120 is produced, it will most likely be a new alkaline earth metal. Alkali metals are also strongly basic and form solid bicarbonates. Polyhalides of Cs are thermally more stable. The solubility of the most of alkali metal halides except those of fluorides decreases on descending the group since the decrease in hydration energy is more than the corresponding decrease in the lattice energy. 1800-212-7858 / 9372462318. So, solubility should decrease from Li to Cs. Beryllium ion is the most soluble and the solubility decreases with increasing size so that Barium ion is the least water-soluble alkaline earth metal ion. Solubility in water is related to the ionic nature and size. The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids). All the bicarbonates (except which exits in solution) exist … The solubility of carbonates decreases from Be to Ba. Solubility of sodium carbonate and calcium carbonate are 30.7 g/100 g water and 0.0013/100 g respectively at 25 0 C. You can see the difference of values. Reactivity decreases down the group. Therefore, for now, we can say that the order is (i) alkali metal perchlorates, (ii) alkali metal bicarbonates, (iv) mercury (II) halides, and (iii) lead (II) halides. The solubility of the most of alkali metal halides except those of fluorides decreases on descending the group since the decrease in hydration energy is more than the corresponding decrease in the lattice energy. Alkali metals belong to the s-block elements occupying the leftmost side of the periodic table.Alkali metals readily lose electrons, making them count among the most reactive elements on earth. This gives them the largest atomic radii of the elements in their respective periods. So the order of solubility- LiHCO3 why cu 1 compounds are white and diamagnetic and cu 2 compounds are coloured and paramagnetic.
