🧠 Memory Aids
Diamond = 4 bonds = hard, Graphite = 3 bonds + 1 free = conducts + slides:
- Diamond: 4 bonds used → ALL electrons locked → NO conduction, VERY HARD
- Graphite: 3 bonds used → 1 electron free per C → CONDUCTS, soft layers SLIDE
Uses memory trick: "Diamond CUTS, Graphite WRITES" — diamond's hardness makes it ideal for cutting tools and drill bits; graphite's layered structure means layers rub off onto paper in pencils.
Allotropes: "ALL-otropes = ALL the same element, different structures" — diamond, graphite, graphene, fullerenes are all made entirely of carbon atoms arranged differently.
