A mineral determined by using fingernailpenny or nail?
A mineral can be tested for hardness using a fingernail, penny, or nail, which are common items that serve as reference points on the Mohs scale of mineral hardness. For instance, a fingernail has a hardness of about 2.5, while a copper penny is around 3.5. If a mineral can be scratched by a fingernail, it is softer than 2.5; if it can be scratched by a penny but not a fingernail, it falls between 2.5 and 3.5. This simple test helps in identifying the mineral's hardness and assists in classification.

A mineral that can be scratched by a penny (which has a hardness of about 3.5 on the Mohs scale) but not by a fingernail (which has a hardness of about 2.5 to 3) would have a hardness between 3 and 3.5. This means the mineral's hardness is likely around 3.2 to 3.4, indicating it is softer than the penny but harder than a fingernail. Examples of minerals that fit this description could include calcite or gypsum, depending on their specific characteristics.
