The most probable reason that the alkaline earth metals give dipositive ions instead of unipositive ions is that

A

the values of their `IE_(1)` and `IE_(2)` are not very different

B

the compound with dipositive ions are highly hydrated in aqueous solution and have high lattice energy in solid state

C

the compound with unipositive ions of these elements are not stable

D

none of the reasons is correct

Text Solution

Verified by Experts

The correct Answer is:
