s - block Elements (Alkali and Alkaline Earth Metals)
The lightest metal among the following is:
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?
The atomic/ionic size of Na and K is larger than that of Mg and Ca.
Hydroxides and carbonates of Na and K have lower lattice enthalpies than those of Ca and Mg. This results in high solubility for hydroxides and carbonates of Na and K whereas those of Mg and Ca are sparingly soluble.
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.
Which of the following oxides is most acidic in nature?
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.
$$CaCl_2$$ 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 :
