talc, gypsum
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by a fingernail.
The most commonly known mineral that can be scratched with a fingernail is talc.
Marginally. Halite has a hardness of 2 to 2.5, about the same as a fingernail.
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 mineral that fits this description is graphite. Graphite is very soft and can be easily scratched by a fingernail. It has a metallic luster and a black streak.

The mineral that has a similar hardness to a fingernail is gypsum. Gypsum has a Mohs hardness of 2, which makes it soft enough to be scratched by a fingernail.
The most commonly known mineral that can be scratched with a fingernail is talc.
Yes. But only soft ones such as talc (solid form of chalk and baby powder). Generally only minerals below 2 on the hardness scale.
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.

Halite is hard. It can be scratched by a steel file and a knife with difficulty
soapstone
Yes, graphite is a relatively soft mineral with a hardness of 1-2 on the Mohs scale. This means it can be easily scratched by materials with a higher hardness, such as a fingernail, which typically has a hardness of around 2.5.
