i believe it is diamond
The softest known mineral is 'TALC'. The hardest known mineral is 'DIAMOND' (according to Friedrich Mohs scale)
The hardest mineral is diamond, which has a hardness of 10 on the Mohs scale.
i think sulfur is the softest and crystal is hardest
The hardest mineral is diamond, and the softest mineral is talc.
On the Mohs scale of relative mineral hardness, diamond is the hardest at 10.
Scratching a mineral with a nail is a test of hardness. The Mohs scale of mineral hardness ranks minerals from 1 (softest) to 10 (hardest), with talc being the softest and diamond being the hardest. If a mineral can be scratched by a nail (with a hardness of around 2.5), it would be classified as having a hardness lower than 2.5 on the Mohs scale.
Diamond is the hardest mineral, scoring a perfect 10 on the Mohs scale of mineral hardness.
Diamond, with a hardness of 10 on the Mohs scale.
Diamond is the hardest mineral and ranked as number '10' according to the Mohs hardness scale.The Mohs scale minerals from softest to hardest:1. Talc (softest)2. Gypsum3. Calcite4. Fluorite5. Apatite6. Feldspar7. Quartz8. Topaz9. Corundum10. Diamond (hardest)
diamond
A diamond and talc
10 is the hardest mineral on the scale. Since Mohs understood this to be the diamond (based on tests scratching different minerals) the diamond was designated a 10.
