Yes: not a good use for a diamond, but yes, a diamond will scratch a nail.
No. Only another diamond can scratch a diamond.
The only thing or mineral that will scratch diamond is another diamond. Scientists use a penny nail and fingernail to see what number it is. On a scale measured from 1-10 diamond is 10 ranked as hardest mineral, so nothing scratches diamond except diamond.
Hard substances are those which are difficult to scratch. For instance candle wax is not hard, you can scratch it with your finger nail. This means your nail is harder than wax. However, an iron nail could scratch your finger nail, but not the other way round, so an iron nail is quite hard. Diamond is the hardest natural substance.
A diamond can scratch a diamond, but one diamond cannot scratch itself.
A steel nail cannot scratch minerals that are harder than itself, which has a Mohs hardness of about 4.5. This means it cannot scratch minerals such as quartz (hardness 7), topaz (hardness 8), corundum (hardness 9), and diamond (hardness 10). These minerals possess greater hardness and will resist scratching by a steel nail.
No. Only a diamond can scratch another diamond.
Nope! A diamond is the hardest substance on earth so only a diamond can scratch a diamond!
Yes, in fact, it is the only way to scratch a diamond.
A mineral's hardness can be determined using a fingernail, penny, or nail by testing its ability to scratch or be scratched by these objects. The Mohs scale of hardness ranks minerals from 1 (talc) to 10 (diamond), with a fingernail typically rated at 2.5, a penny at about 3.5, and a nail around 5.5. By attempting to scratch the mineral with these items, you can estimate its hardness based on which objects can scratch it and which cannot.
Diamond is harder than steel: you can scratch steel with a diamond, but steel will not scratch a diamond.
noNo other way around
Diamond will scratch everything, including diamond.
