No. Hardness is measured on the Mohs Scale, named after German Friedrich Mohs. On this scale Talc (the softest) measures 1, while Diamond (the hardest) measures 10.
Glass has a Mohs' scale hardness of around 5.5, so anything above that will have the ability to scratch glass. For example, quartz (Mohs 7), hardened steel (Mohs 8), corundum (rubies and sapphires, Mohs 9),or diamond (Mohs 10).
The Mohs scale is purely an ordinal scale, expressing relative hardness in a simplistic way. Carborundum (Mohs 9) is twice as hard as Topaz (Mohs 8), but diamond (Mohs 10) is four times harder than arborundum.
Diamond is a harder mineral than the minerals used to make glass.
Because Diamond is one of the hardest substances known to man. Chalk is very soft.
Diamond is the hardest natural mineral, and will scratch glass, because glass is softer than diamond.
It is a physical change because any chemical reaction is involved.
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.
Diamond are only scratched by diamonds.
Diamond will scratch anything.
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 almost any mineral that isn't diamond.
A diamond can scratch a diamond, but one diamond cannot scratch itself.
Diamonds are harder than chalk.
No. Only a diamond can scratch another diamond.
gympsum can scratch diamond
A diamond will scratch anything and everything, including another diamond.
No. Diamond will scratch steel, however,
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.
Yes, in fact, it is the only way to scratch a diamond.
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.
