Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
Halite has a hardness of 2.5 on the Mohs scale, while a fingernail has a hardness of about 2.5 as well. Therefore, halite can be scratched by a nail.
It can be scratched by a diamond, corundum, topaz, and quartz.
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
If a mineral can be scratched by a streak plate but not by a masonry nail, it indicates that the mineral has a hardness less than that of the streak plate but greater than that of the masonry nail. The Mohs hardness scale helps to categorize minerals based on their scratch resistance, with the streak plate typically having a hardness of about 6. The masonry nail, being softer, has a hardness lower than 6, allowing the mineral to resist scratching by it.
Yes.
Calcite is a mineral that can be easily scratched by a steel nail due to its relatively low hardness compared to steel.
No, sulfur is harder than a nail so it cannot be scratched by a nail. Nails are typically made of iron, which is softer than sulfur. Therefore, if a nail comes into contact with sulfur, the nail is more likely to scratch than the sulfur.
Halite has a hardness of 2.5 on the Mohs scale, while a fingernail has a hardness of about 2.5 as well. Therefore, halite can be scratched by a nail.
It can be scratched by a diamond, corundum, topaz, and quartz.
A very soft rock like gypsum or talc would be scratched easily with a finger. Rocks like quartz, granite, or diamond would not be scratched by a finger.
Yes. It is much harder than your fingernail.
No. Only another diamond can scratch a diamond.
Yes, nickel is softer than steel, so it is possible for a nail to scratch nickel.
Yes. A steel nail has a Mohs hardness greater than that of fluorite.
No, sulfur cannot be easily scratched by a nail because it is a relatively soft material compared to metals like iron or steel. Sulfur has a Mohs hardness of 1.5–2, while iron nails typically have a hardness of 4-5 on the Mohs scale.
Yes, because talc is very soft.
