The Correct Option is A
Solution and Explanation
Calcium reacts with oxygen to form calcium oxide (CaO), which has a high melting point. Additionally, calcium oxide is soluble in water, forming a basic solution (calcium hydroxide, Ca(OH)₂).
Therefore, the correct answer is (A): calcium.

- Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): Type B metal ions form more stable complexes compared to Type A metal ions.
Reasons (R): High electro-negativity (in relative terms) of metal and low electro-negativity of the legand donor atom would be consistent with stability of a complex with Type B metal ion.

- Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Stability of most complexes with the alkaline earth metals is in the order Mg2+ > Ca2+ > Sr2+> Ba2+
Reason R :For type A ions, Electrostatic model approximately explain the stability of metal-ligand complexes that is, stability of these complexes is positively correlated with the ratio of Z2/r for both metal ion and the ligand species.
