A harder mineral will scratch a softer one.
You can tell if a mineral can scratch another mineral by performing a scratch test, where you use the hardness scale to compare the minerals. If the mineral you are testing can scratch the other mineral, then it has a higher hardness on the scale.
Most likely you would be testing to see if the mineral was harder or softer than the nail.
it is hardness
Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !
false a mineral can not scratch any mineral harder than itself
A diamond is the only material that cannot be scratched by any other than itself.
Halite can scratch gypsum.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
When a mineral can scratch another mineral, it means that the mineral is harder than the mineral it can scratch. Hardness is a measure of a mineral's resistance to being scratched, with the Mohs scale commonly used to rank minerals based on their hardness.
According to the Mohs scale of hardness, Diamond has a hardness of 10 and Quartz has a hardness of 7. Any mineral with a hardness greater than 7 can scratch quartz and diamond can scratch any mineral with a hardness less than 10. Corundum (hardness of 9) and Topaz (hardness of 8) are two examples of minerals that can scratch quartz but not diamond.
Corundum can scratch all minerals except diamond, making it the second hardest mineral on the Mohs scale with a hardness of 9. Diamond, with a hardness of 10, is the only mineral that can scratch corundum.
