Answer 2

magnesium

Step-by-step explanation:

Magnesium oxide is a crystalline compound, so that its atoms are organized, a base cell that repeats itself, with the formation of a crystal lattice. The bond between magnesium and oxygen atoms is ionic, therefore it is characterized by being strong and stable in nature. Its crystalline structure is a cubic structure centered on the faces.
