False. A mineral can only scratch itself or minerals equal in hardness or softer than it.
A diamond is the only material that cannot be scratched by any other than itself.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
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.
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
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.
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
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.
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.
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.
Diamonds are proven to scratch all minerals including itself.
Talc is the mineral that cannot scratch any mineral by itself. It has a Mohs hardness of 1, making it the softest mineral on the Mohs scale, which means it can be easily scratched by all other minerals.
Talc is the softest mineral on the Mohs scale with a hardness of 1, so it can be easily scratched by harder minerals. Talc can scratch over minerals with a lower hardness value, but it cannot scratch minerals that are harder than itself, such as quartz or diamond.
Talc can scratch Talc , although Talc's hardness varies it is considered a soft mineral, that can even be scratched with a finger nail. Any mineral or material with a hardness equal to or greater than 1 on the Mohs hardness scale will be able to scratch talc. Talc is the softest mineral listed on the Mohs scale, listed as a 1 on the scale which is graded from 1 through 10, with 10 being the hardest (diamond).
Diamond will scratch all rocks and other minerals, including itself.
