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.
What mineral is softer than a human fingernail?
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.
Which mineral is softer than a fingernail?
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.
If you scrape a rock with your fingernail and your fingernail leaves a scratch it must be?
Your nail is 2.5 so the rocks you can scratch are, Gypsum and Talc.
What mineral can be scratched by a penny but not a fingernail?
Copper sulfide minerals, such as chalcocite and bornite, can be scratched by a penny but not a fingernail. This is due to the Mohs hardness scale, where these minerals have a hardness greater than a penny (3.5) but less than a fingernail (2.5).

Are there any minerals softer than talc?
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.
What can scratch gypsum but can be scratched by all other minerals?
Talc can scratch gypsum, but can be scratched by all other minerals. Talc is the softest mineral on the Mohs scale, with a hardness of 1, making it easily scratched by minerals with higher hardness values. Gypsum has a Mohs hardness of 2, so talc can leave a mark on it.

What minerals are softer than gold?
Minerals that are softer than gold include talc, gypsum, and calcite. These minerals have a lower hardness level on the Mohs scale compared to gold, which has a hardness of about 2.5 to 3.
What is the classification of a rock that cannot ba scratched with a fingernail but can be scratched with a coin?
The rock would likely be classified as having a hardness of around 3.5 on the Mohs scale of mineral hardness. This would indicate that the rock is softer than minerals like quartz but harder than minerals like calcite. Examples of rocks with this hardness include gypsum and calcite.
Are harder minerals more useful than softer minerals?
Not necessarily. Both harder and softer minerals have valuable uses depending on their properties. Harder minerals like diamonds are useful for cutting and grinding, while softer minerals like talc are used in products like talcum powder. It really depends on the specific application.
