Talc (1 on the Mohs Hardness Scale) can be scratched by a fingernail.
The mineral that can be scratched by a penny is talc. Talc is the softest mineral on the Mohs scale, with a hardness of 1. A penny has a hardness of around 3.5 on the Mohs scale.
Mineral hardness measures the resistance of a mineral to scratching or abrasion. It is determined by the ability of a mineral to scratch another mineral or be scratched by it, as defined by the Mohs scale of hardness.
A mineral's resistance to being scratched is known as it's hardness. You can determine hardness by scratching it with another material whose hardness is already known. If it can be scratched, then the hardness is lower. If the unknown leaves a scratch on the known material, then its hardness is higher.
Gypsum is a mineral commonly found in drywall that is easily scratched due to its low hardness on the Mohs scale of mineral hardness.
Scientists use the Mohs scale of mineral hardness to determine the relative hardness of minerals. This scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals. By performing a scratch test, scientists can identify a mineral's hardness by comparing it to known minerals on the Mohs scale.

A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
The Mohs mineral hardness scale.
Talc is the softest mineral on the Mohs hardness scale. It has a hardness of 1 and can be easily scratched by other minerals.
Gypsum is a mineral commonly found in drywall that is easily scratched due to its low hardness on the Mohs scale of mineral hardness.
Scientists use the Mohs scale of mineral hardness to determine the relative hardness of minerals. This scale ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals. By performing a scratch test, scientists can identify a mineral's hardness by comparing it to known minerals on the Mohs scale.
True, hardness is determined by how easily a mineral can be scratched. The Mohs scale is commonly used to measure hardness, with higher numbers indicating greater hardness.
The Mohs scale of mineral hardness is used to measure the scratch resistance of a mineral. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by another mineral. The scale is a qualitative measure that helps in identifying minerals based on their hardness.
This property is known as the hardness of the mineral. It is determined by the strength and arrangement of atoms within the mineral's structure, affecting how easily it can be scratched by other materials. Hardness is measured using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest).
Minerals have a fairly specific range of hardness, based on the Mohs hardness scale. The Mohs scale is based on the ability of a mineral to be scratched, or scratch, another mineral. Using the Mohs scale to determine mineral hardness is one test that can be used to help identify one mineral from others.
