On the Mohs scale, what is the hardness of talc?

Explanation:
On the Mohs scale, hardness is about how easily a mineral can be scratched. Talc is the softest mineral, occupying the lowest rating on the scale. That means it can be scratched very easily, even by a fingernail, and it can powder with little effort. The other values correspond to minerals that are harder than talc, so they don’t describe talc’s true softness. Thus, talc has the softest rating on the scale.
