Metallic Bonding (AQA A-Level Chemistry): Flashcards

Attraction between positive metal ions and delocalised electrons

Positive ions in regular pattern surrounded by sea of delocalised $e^-$

Outer electrons free to move throughout the structure

Delocalised electrons are free to move

Electrostatic attraction between positive ions and delocalised $e^-$

Stronger metallic bonds (more delocalised electrons)

$\text{Mg}^{2+}$ stronger bonding than $\text{Na}^{+}$

Weaker bond due to larger atomic radius

Weaker due to larger atomic radius

Conductivity and malleability
