Looking at Moh's hardness scale, which mineral is the hardest?talcdiamondglassflint

The hardest mineral on Moh's hardness scale is diamond. Moh's hardness scale ranges from 1 to 10, where talc is rated at 1 (the softest) and diamond is rated at 10 (the hardest).

Diamonds are renowned for their exceptional hardness, attributed to the strong covalent bonding between carbon atoms in their crystal lattice structure. This unique arrangement enables diamonds to withstand scratching and abrasion, making them highly valued not only in jewelry but also in industrial applications where hard materials are required.

In contrast, talc, the softest mineral, can be easily scratched with a fingernail, while glass and flint have varying hardness levels but are significantly softer than diamond according to the scale.

In summary, among the given options (talc, diamond, glass, flint), the hardest mineral is diamond.
