Correct, a 5 hardness can scratch a 5 and below.
it is hardness
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
false a mineral can not scratch any mineral harder than itself
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 !
Fluorite is unable to scratch feldspar, quartz, corundum, diamond, or any other mineral with a Mohs hardness greater than 4.
it is hardness
It is called a streak and its purpose is to find the hardness of the mineral.
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.
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.
When you scratch a mineral with a penny, nail, and your fingernail, you are testing the mineral's hardness. The ability to scratch or be scratched by certain materials helps determine the mineral's hardness on the Mohs scale of mineral hardness.

its ability to scratch another mineral
Mineral hardness measures the resistance of a mineral to scratching or abrasion. It is determined by the ability of a mineral to scratch another mineral or be scratched by it, as defined by the Mohs scale of hardness.
False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
diamond's hardness is a factor of 10. So this is the highest hardness, no mineral has this hardness! You can't scratch a diamond.
