yes
No......Topaz is an 8 and Talc is a 1....talc is the softest on the scale
A copper penny can scratch materials with a Mohs hardness of 2.5 or lower, such as gypsum, talc, and some plastics. It will not scratch harder materials like glass, steel, or most ceramics.
you can scratch talc becuase it is the softest mineral on the moth scale.
topaz has a hardness of 8 on the mohs hardness scale, quartz has a hardness of 7. topaz will be able to scratch quartz, but quartz can never scratch topaz.
A steel knife can scratch minerals with a hardness lower than that of steel, such as gypsum, calcite, fluorite, and talc. Minerals like quartz, topaz, and corundum are harder than steel and cannot be easily scratched by a steel knife.
A penny would scratch minerals with a lower hardness rating such as calcite, gypsum, or talc. Minerals like quartz or topaz would not be scratched by a penny because they are harder than the metal in a penny.
No, apatite cannot scratch topaz. On the Mohs scale of mineral hardness, apatite has a hardness of 5, while topaz has a hardness of 8. This means that topaz is significantly harder than apatite and can easily scratch it.
apatite will not scratch quartz topaz calcite or corundum
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.

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.
