Magnesium form Mg2+ and not Mg+ because

Question

Magnesium form Mg2+ and not Mg+ because (A) magnesium (II) carbonate is insoluble in water (B) generally higher oxidation states are preferred by metals (C) ionic radius of Mg(II) is smaller than that of Mg(I)  (D) hydration energy of divalent magnesium ion is higher than monovalent magnesium ion.

Hydration energy for Mg2+ > Hydration energy for Mg+ , hence Mg forms dipositive ion

Q. Magnesium form $M g^{2 +}$ and not $M g^{+}$ because

magnesium $(II)$ carbonate is insoluble in water

generally higher oxidation states are preferred by metals

ionic radius of $M g (II)$ is smaller than that of $M g (I)$

hydration energy of divalent magnesium ion is higher than monovalent magnesium ion.

Hydration energy for $M g^{2 +}$ > Hydration energy for $M g^{+}$ , hence $M g$ forms dipositive ion
