Concepts in Inorganic Chemistry - Lecture 10 | Lattice Energy & Born–Lande Equation Explained

Описание: Welcome to Concepts in Inorganic Chemistry I | Lecture 10: Lattice Energy ⚛️

In this lecture, we explore one of the most important energetic concepts in ionic bonding — lattice energy. You will learn how ions come together to form stable ionic crystals, how lattice energy is calculated theoretically, and how it influences the properties of ionic compounds.

🎯 Topics Covered:
• What is lattice energy?
• Formation of ionic solids from gaseous ions
• Heat of formation vs lattice energy
• Attractive & repulsive interactions in ionic lattices
• Madelung constant, Born exponent & ionic distances
• Derivation of the Born–Lande Equation
• Experimental vs theoretical lattice energy (Born–Haber cycle)
• Assumptions behind lattice energy calculations
• Factors affecting lattice energy:
– Ionic charge
– Ionic radius
– Interionic distance
• Ranking compounds by lattice energy (practice questions)

💡 Why Watch:
A solid understanding of lattice energy helps explain stability, melting point, solubility, bond strength, and many trends in inorganic chemistry. Ideal for university students, A/L chemistry learners, and anyone studying bonding energetics.
