Sulfur is a relatively soft element. Its Mohs hardness is 1.5 to 2.5.

This means that sulfur can be scratched by a fingernail (hardness 2.5) but not by a copper coin (hardness 3.5).

Here's a little more about its properties:

* Crystalline Sulfur: Sulfur can exist in various crystalline forms, with varying degrees of hardness.

* Amorphous Sulfur: Amorphous sulfur is softer than crystalline sulfur.
