Answering the Question

The Mohs Hardness Scale is a qualitative scale that characterizes the scratch resistance of various minerals through the ability of harder minerals to scratch softer ones.

1. Understanding Mohs Hardness Scale: The scale ranges from 1 to 10, with talc being the softest (1) and diamond being the hardest (10). Each mineral is designated a specific hardness number based on its ability to scratch the mineral below it.

2. Identifying the Hardest Mineral:

   • Talc (1)
   • Gypsum (2)
   • Quartz (7)
   • Diamond (10)

Among the options provided—talc, quartz, diamond, and gypsum—the hardest mineral is diamond, which has a hardness rating of 10 on the Mohs scale. This makes it not only the hardest mineral listed but also the hardest known natural material.

Final Answer

Diamond is the hardest mineral in the Mohs Hardness Scale.
