What is the crystal structure of Magnesium? Correct Answer Hexagonal close packed structure

HCP is abbreviated as hexagonal close packed structure. Conditions for HCP is a1=a2≠a3 and α=β=60, γ̈=120, where a1, a2, a3 are unit vectors in three directions and α, β, γ̈ are angles between them. Magnesium possesses an HCP crystal structure.
