Examples of Metallic Bonding in Everyday Life

📚 Quick Study Guide

• 🔩 Metallic bonding involves the sharing of electrons within a 'sea' of electrons.
• ⚡ This electron sea enables high electrical and thermal conductivity.
• 🔨 Metals are malleable (can be hammered into shapes) and ductile (can be drawn into wires) because the metallic bonds allow atoms to slide past each other.
• ✨ Strength of metallic bond increases with the number of valence electrons and decreases with increasing atomic radius.
