Talc i assigned a hardness of 1 according to the Mohs scale of hardness. This implies that talc has the least hardness and therefore is soft and can be scratched by a fingernail.
The most commonly known mineral that can be scratched by a fingernail is talc.
Talc (1 on the Mohs Hardness Scale) can be scratched by a fingernail.
The most commonly known mineral that can be scratched with a fingernail is talc.
Minerals that are soft enough to be scratched by a fingernail include gypsum (2 on the Mohs scale), talc (1), and calcite (3).
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.

Talc and gypsum are two minerals that can be scratched with a fingernail due to their low hardness on the Mohs scale.
Talc is the softest mineral on the Mohs hardness scale, with a rating of 1. It can be easily scratched with a fingernail.
Quartz (Mohs 7.0) and diamond (Mohs 10,0) are two of many minerals that are harder than copper (Mohs 2.5-3.0).
The softest rock is talc, which is the primary mineral in talcum powder. It has a hardness of 1 on the Mohs scale, meaning it can easily be scratched with a fingernail. Talc is often used in cosmetics and personal care products due to its softness and ability to absorb moisture.
Talc has a Mohs hardness scale rating of 1, making it one of the softest minerals. It is easily scratched by harder substances like a fingernail or a copper penny.
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.
