This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 9 of 12 in this topic. Use it for quick recall, then test yourself straight afterwards so the memory aid becomes usable in an answer.
🧠 Memory Aids
Metal = SEA of electrons flowing freely: Imagine a vast ocean — the positive metal ions are like buoys bobbing in the ocean, and the electrons are the water flowing freely around them. The ocean holds the buoys in place while still being able to flow — explaining both the structure and the conductivity.
Property mnemonics:
- MaDe Cm — Malleable, Ductile, Conducts (electricity and heat), high Melting point
Metal vs Ionic conductivity: "Metal conducts ALWAYS (solid), Ionic conducts ONLY when ions can move (molten/dissolved)"
Stronger metallic bonding: More electrons released = stronger. Na (1 e⁻) < Mg (2 e⁻) < Al (3 e⁻) in terms of metallic bond strength.
Practice questions for Metallic Bonding
In metallic bonding, what are the electrons called that are free to move throughout the metal structure?
Explain why metals are malleable.
