🔹 Title Suggestion:
Hexagonal Close-Packed (HCP) Unit Cell | Solid State Chemistry Lecture
📌 Description:
Welcome to today’s Solid State Chemistry lecture! In this video, we explore the Hexagonal Close-Packed (HCP) unit cell—one of the most important crystal structures in materials science.
👉 What you’ll learn:
Structure of the HCP unit cell
ABAB stacking sequence explained
Atomic positions and effective atom count (6 atoms/unit cell)
Geometry, lattice parameters, and ideal c/a ratio
Coordination number and packing efficiency (74%)
Examples of metals with HCP structure (Mg, Ti, Zn, Co, Cd)
✨ Easy analogies, clear diagrams, and exam-focused explanations make this lecture perfect for students preparing for IIT-JEE, NEET, CSIR-NET, GATE, and other competitive exams.
