Yes
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.
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.
Nickel leaves a silver-gray streak. Note that nickel is an element.
This mineral is likely quartz. Glass has a hardness level of around 5.5, while quartz has a hardness of 7. A nail, which is made of iron, generally has a hardness around 4.
All zinc nails rust over a long period of time. One that has been scratched will rust sooner. You could touch over with a zinc paint. I would need to know more. I cant see any problems.
Yes.
nickel
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.
Yes, sandstone can be scratched by a nail. Sandstone typically has a hardness of around 6 to 7 on the Mohs scale, depending on its composition, which means it can be scratched by materials that are harder, such as steel. Since a typical nail is made of steel, it can easily scratch the surface of sandstone.
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. It is much harder than your fingernail.
No. Only another diamond can scratch a diamond.
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.
