List of top Chemistry Questions on Alkaline earth metals

An element X reacts with air to form monoxide and nitride. This oxide is amphoteric. It can be converted to its chloride by heating with carbon and chlorine. Which of the following is correct for X?
The \(E^\circ_{{M}^+_{(aq)}}/{M}_{(s)}\) is highest with negative sign for alkali metal 'x' and lowest with negative sign for alkali metal 'y'. In flame test, the characteristic colours of 'x' and 'y' are respectively:
Which one of the following alkaline earth metals does not form hydride when it is heated with hydrogen directly?
Two alkali halide salts, \[ \text{ACl} \] and \[ \text{BCI} \] gave crimson red and violet in their flame test respectively. A and B are respectively
Match the following:
List I
(alkaline earth metal)		List II
(density / g cm3)
A. BeI. 1.74
B. MgII. 1.84
C. CaIII. 2.63
D. SrIV. 1.55
The correct answer is
Identify the correct statements from the following:
(a) Alkali metals are strong reducing agents.
(b) KO\(_2\) is a diamagnetic oxide.
(c) Lithium chloride exists as LiCl·2H\(_2\)O.
Identify the correct statements from the following
\[ \text{(a) } BeSO_4 \text{ is soluble in water} \] \[ \text{(b) } BeO \text{ is an amphoteric oxide} \] \[ \text{(c) } CO \text{ can be obtained by heating } CaCO_3 \text{ at } 1070-1270\,K \]
Assertion (A):- \(MgSO_4\) is readily soluble in water
Reason (R):- The greater hydration enthalpy of \(Mg^{2+}\) ions overcomes its lattice enthalpy.
Which of the following alkaline earth metal hydroxides is amphoteric in character?
