False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
false. if a mineral is harder than another mineral, it would be able to scratch the softer one
A diamond is the only material that cannot be scratched by any other than itself.
Most of the time, no. But there are some minerals, such as kyanite, that have more than one hardness in an individual crystal. But this is an exception to the Mohs scale of mineral hardness, which is based on the premise that a mineral of a lower number cannot scratch a mineral of a higher (harder) number.
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
Qtz is a 7 on Mohs Hardness scale. So it can scratch itself or anything less on the scale. Just that simple.
false a mineral can not scratch any mineral harder than itself
No, it is just the opposite.

A diamond is the only material that cannot be scratched by any other than itself.
In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
Most of the time, no. But there are some minerals, such as kyanite, that have more than one hardness in an individual crystal. But this is an exception to the Mohs scale of mineral hardness, which is based on the premise that a mineral of a lower number cannot scratch a mineral of a higher (harder) number.
The hardness of a mineral is categorized on the Mohs hardness scale with talc as 1 and diamond as 10. A mineral can only be scratched bya mineral that is as hard or harder than the first mineral. So talc can scratch talc but nothing else. A diamond can scratch every other mienral including itself. Cordundum with a hardness of 9 can't scratch diamonds but can scratch a lot of other minderals.
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
Diamonds are proven to scratch all minerals including itself.
Diamond will scratch all rocks and other minerals, including itself.
Diamond is the hardest naturally occurring mineral and can scratch all other minerals. Talc is the softest of minerals and cannot scratch any other mineral.
Yes. Any metal or mineral will scratch itself and anything softer than it on the hardness scale.
