A diamond can scratch a diamond, but one diamond cannot scratch itself.
A fingernail has a hardness level of about 2.5 to 3 on the Mohs scale of mineral hardness. This scale measures the scratch resistance of various minerals, with 1 being talc and 10 being diamond. The relatively low hardness of fingernails makes them susceptible to scratches and damage from harder materials.
You could perform a scratch test by trying to scratch one mineral with another. Whichever mineral leaves a mark or scratch on the other is harder. By comparing the results of scratching each mineral with the others, you can determine their relative hardness.
Granite is a hard and durable natural stone, so it is unlikely to be scratched by a fingernail. Fingernails are generally not hard enough to scratch granite surfaces.
it can get scratch by a diamond
Kaolin is a soft white clay used in making porcelain. You can scratch kaolin with your fingernail, so, because diamond is the hardest known mineral, of course a diamond will also scratch kaolin.
Your nail is 2.5 so the rocks you can scratch are, Gypsum and Talc.
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.
No, you cannot get HIV from a fingernail scratch. HIV is transmitted through specific bodily fluids, such as blood, semen, vaginal fluids, and breast milk. Casual contact like a fingernail scratch does not pose a risk for HIV transmission.
Scratch.
A diamond can scratch a diamond, but one diamond cannot scratch itself.
you can scratch talc becuase it is the softest mineral on the moth scale.
Talc is a very soft mineral, ranking as 1 on the Mohs scale of hardness, and your fingernail is harder at around 2.5. This means your fingernail can easily scratch talc due to the difference in hardness levels.
No. Only a diamond can scratch another diamond.
Most scratches from fingernails leave red marks where the scratch occurred.
Nope! A diamond is the hardest substance on earth so only a diamond can scratch a diamond!
Yes: not a good use for a diamond, but yes, a diamond will scratch a nail.
