Alkali Metals - The six elements belonging to group 1 of the periodic table, namely lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr) are called alkali metals. They constitute alkali meta..

All the carbonates of alkali metals are quite stable towards heat except Li 2 CO 3 , which decomposes easily on heating. The instability of Li 2 CO 3 is due to the small size of lithium ion, which cannot stabilize the bigger carbonate ion. The carbonates of alkaline ..

As alkaline Earth metals have low ionization energies and high electropositive character, they are very reactive and have a strong tendency to lose valence electrons, though less than alkali metals. The reactivity of these elements increases on goin..

The solubilities of sulphates of alkaline Earth metals decrease as we go down the group...

Elements of group I A of the periodic table constitute a family of very reactive metals called alkali metals. They are lithium, sodium, potassium, rubidium, cesium and francium. All of them have one electron in the valence shell. They are called h..
