Nitrogen can ionically bond with an unknown element X from group 2. How many ions of element X are required to create a stable ionic compound with nitrogen?

Responses
A 22
B 33
C 44
D There is not enough information.

The correct answer is D.

There is not enough information to determine how many ions of element X are required to create a stable ionic compound with nitrogen. The number of ions required depends on the charges of the ions and the ratio in which they combine.
