Verified step by step guidance1
Understand that the Mohs hardness scale is a qualitative ordinal scale characterizing the scratch resistance of various minerals through the ability of a harder material to scratch a softer material.
Recall that the scale ranges from 1 to 10, where 1 represents the softest mineral (Talc) and 10 represents the hardest mineral.
Identify the minerals listed in the problem and their typical Mohs hardness values: Talc (1), Calcite (3), Quartz (7), and Diamond (10).
Recognize that the mineral with the highest Mohs hardness value is considered the hardest naturally occurring mineral on Earth.
Conclude that since Diamond has a Mohs hardness of 10, it is the hardest mineral among the options provided.
