s - block Elements (Alkali and Alkaline Earth Metals)
The lightest metal among the following is:
Which of the following oxides is most acidic in nature?
As we know that the acidic character of oxides increases across the period while it decreases down the group. Therefore, the acidic character of oxides follows the order:
$$BeO>MgO>CaO>BaO$$
Therefore, $$BeO$$ is most acidic.
The lightest metal among the following is:
Size of hydrated ion of $$Li^+ and Be^{2+} $$ is :
Compare the solubility and thermal stability of alkali metals carbonates with those of the alkaline earth metals nitrates.
The correct order of solubility of the following compound in water is:
Compare the solubility and thermal stability of the following compounds of the alkali metals with those of the alkaline earth metals. (a) Nitrates, (b) Carbonates, (c) Sulphates.
The hydroxides and carbonates of sodium and potassium are easily soluble in water while the corresponding salts of magnesium and calcium are sparingly soluble in water. Explain?
$$CaCl_2$$ is preferred over $$NaCl$$ for clearing ice on roads on particularly in very cold countries. This is because:
Alkaline earth metals are better reducing agents than alkali metals.
Which of the following groups of elements have chemical properties that are most similar :
If $$X$$ and $$Y$$ are the second ionisation potentials of alkali and alkaline earth metals of same period, then :
