Which of the following will not form crystalline structure with opporitely charged ions_________________?
Correct answer: A. H+
- A. H+
- B. H-
- C. Mg2+
- D. Ca2+
Explanation
An ionic crystal requires a stable lattice of oppositely charged ions, but H+ is only a proton with no electron cloud and does not form an ordinary ionic crystal lattice as an isolated ion. H- can act as an anion and can combine with suitable cations, so students may incorrectly choose H- by overlooking the special nature of H+.

About Shape of Ionic Crystals
Ionic crystal shape depends on the regular arrangement of oppositely charged ions in a three-dimensional lattice. The topic covers coordination number, radius ratios, lattice geometry and structures such as sodium chloride, caesium chloride and zinc sulfide, which should not be confused with the molecular shapes predicted by VSEPR theory.
