* Elemental arsenic: This form is a brittle, steel-gray solid with a metallic luster. It's somewhat soft, similar in hardness to lead.

* Arsenic compounds: These are much more diverse in their texture depending on the specific compound. Some common examples include:

* Arsenious oxide (As2O3): This is a white, crystalline powder that can also exist in a glassy form.

* Sodium arsenite (NaAsO2): This is a colorless, crystalline solid that is soluble in water.

* Arsenic sulfide (As2S3): This is a yellow, crystalline solid that is insoluble in water.

So, the texture of arsenic depends on the specific form you're talking about. Elemental arsenic is a brittle, steel-gray solid, while arsenic compounds can have a range of textures from powdery to crystalline.

It's important to note that arsenic is a highly toxic substance and should never be handled without proper safety precautions.
