Which mineral is the hardest according to the Mohs hardness 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)
What mineral has a hardness of 10 on the Mohs hardness scale?

What mineral has the lowest hardness on the Mohs hardness scale?

What 2 ways can minerals break?
Minerals break in the main two ways cleavage and fracture. Cleavage is breaking in flat planes but fracture is more uneven even unpredictable. The hardest mineral to break would be the diamond, which is placed at a ten on Moh's hardness scale.
How is the Mohs scale of mineral hardness used?
The Mohs scale is used to aid in quick field identification of minerals, along with other techniques. Mohs based the scale on ten minerals that are all readily available. As the hardest known naturally occurring substance, diamond is at the top of the scale. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, and/or the softest material that can scratch the given material. For example, if some material is scratched by apatite but not by fluorite, its hardness on the Mohs scale would fall between 4 and 5. Hardness Mineral 1 Talc (Mg3Si4O10(OH)2) 2 Gypsum (CaSO4·2H2O) 3 Calcite (CaCO3) 4 Fluorite (CaF2) 5 Apatite (Ca5(PO4)3(OH-,Cl-,F-) 6 Orthoclase (KAlSi3O8) 7 Quartz (SiO2) 8 Topaz (Al2SiO4(OH-,F-)2) 9 Corundum (Al2O3) 10 Diamond (C)

What is the hardest of all the rocks?
Hardest Mineral=Diamond Second would be corundum.etc. etc....but these are minerals. Rocks are a combination of at least 2 minerals. A hard "rock" would be nearly any mafic, igneous rock.

Which mineral has a hardness of 2?
Gypsum is the mineral listed at 2 on the Mohs hardness scale.
What is the softest mineral and why?
Talc is the softest mineral. The Mohs hardness scale goes like this, from softest to hardest: 1. Talc, 2. Gypsum, 3. Calcite, 4. Fluorite, 5. Apatite, 6. Orthoclase Feldspar, 7. Quartz, 8. Topaz, 9. Corundum, 10. Diamond.
