MgO has the same crystal structure as NaCl, face-centered cubic. How many oxide ions surround each Mg²⁺ ion as nearest neighbors A) 4 B) 6 C) 8 D) 10 E) 12

Question

Quizplus · Accepted Answer

In a face-centered cubic (FCC) structure like NaCl, each cation is surrounded by 6 anions and vice versa. Therefore, each Mg²⁺ ion is surrounded by 6 oxide ions as nearest neighbors.
