Do you mean elemental (metallic) zinc or a zinc mineral (like sphalerite, smithsonite)? Quick answers for both:
- Elemental zinc (metal)
- Cleavage: none/insignificant — metals don’t show the crystallographic cleavage typical of many minerals.
- Transparency: opaque (metallic luster); not transparent.
- Fracture: at room temperature zinc is relatively brittle and breaks with an uneven/granular or hackly surface; it becomes malleable/ductile when heated (~100–150 °C).
- Common zinc ore — sphalerite (ZnS)
- Cleavage: very good/perfect on {110} (dodecahedral directions).
- Transparency: ranges from transparent to opaque depending on impurities and crystal quality.
- Fracture: conchoidal to uneven.
If you meant a different zinc mineral, tell me which one and I’ll give its specific properties.
