On the Mohs hardness scale, Stibnite is about 2 while fingernails are about 2.2-2.5. This means that stibnite is softer than a fingernail, but only slightly.
Talc is a mineral that is softer than a human fingernail, measuring only 1 on the Mohs scale of mineral hardness. It is commonly used in baby powder and cosmetics due to its soft texture.
Talc and gypsum are two minerals that are softer than a human fingernail. Talc has a hardness of 1 on the Mohs scale, while gypsum has a hardness of 2.
Talc and gypsum are two minerals that are softer than a human fingernail, which has a hardness of about 2.5 on the Mohs scale. Talc has a hardness of 1, while gypsum has a hardness of 2.
Your nail is 2.5 so the rocks you can scratch are, Gypsum and Talc.
Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
Talc is a mineral that is softer than a human fingernail, measuring only 1 on the Mohs scale of mineral hardness. It is commonly used in baby powder and cosmetics due to its soft texture.
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.

Gypsum is a mineral, with the chemical formal CaSO4(H2O)2. It is soft and is an index mineral for Moh's Hardness Scale, with a hardness of 2. It is softer than a fingernail. It is in the monclinic crystal system and is commonly used in agriculture, manufacture of ceramics and sheet rock.
There are no other minerals that are softer than talc. On Moh's hardness scale, diamonds are the hardest mineral, and talc is the softest mineral in the world.

Pyrite is a mineral that is softer than calcite, has a metallic luster, and exhibits cubic cleavage.
The fingernail test is for minerals and if a mineral is soft then you stick your fingernail in the mineral and if it is below 10 on the moh's hardness scale then it can put a dent into the mineral hope that helps!!
The mineral that is soft and metallic is talc. Talc is known for its greasy feel and can be easily scratched with a fingernail, making it one of the softer minerals on the Mohs scale.
