🔬 Understanding Metallic Bonding in Detail
What actually happens in metallic bonding:
• Each metal atom releases its outer electrons into a shared "pool"
• E.g., sodium releases 1 electron per atom; magnesium releases 2
• The more electrons released, the stronger the metallic bonding
• The remaining atoms (now with fewer electrons than protons) become positive ions
• These ions are arranged in a regular, close-packed structure
• The arrangement is fixed and ordered (like ionic lattices)
• The released electrons move freely throughout the entire metal
• They are not attached to any single atom — they are "delocalised"
• These electrons fill the space between positive ions
• Positive ions and negative electrons attract each other strongly
• This electrostatic attraction holds the structure together
• The bond acts throughout the whole metal simultaneously
Comparing bonding types: Ionic, covalent, and metallic bonding all involve electrostatic attraction. In ionic: between ions. In covalent: between nuclei and shared electrons. In metallic: between positive metal ions and the delocalised electron sea.
Why some metals have higher melting points than others:
• More electrons released per atom → stronger bonding
• Mg²⁺ has stronger metallic bonding than Na⁺ (2 electrons vs 1)
• Smaller ions → ions closer to electrons → stronger attraction
• This explains why magnesium has higher MP than sodium
