1.	What is the crystal structure of Magnesium?(a) Face centered cubic structure(b) Body-centered cubic structure(c) Hexagonal close packed structure(d) Simple cubic structureThis question was posed to me by my college director while I was bunking the class.My question comes from Principles topic in division Corrosion Principles of Corrosion Engineering
Answer» The correct option is (c) HEXAGONAL close packed structure The explanation is: 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.
