Gypsum is the mineral listed at 2 on the Mohs hardness scale.
Friedrich Mohs is famous for creating the Mohs scale of mineral hardness. He formulated a scale of one to ten and assigned each mineral a value. This eventually became the basis for the Mohs scale.
This scale was proposed by the Austrian geologist Friderich Mohs.
Galena is listed at 2.5 on the Mohs scale of mineral hardness.

The fourth mineral on Mohs' Scale of Hardness is fluorite. It has a hardness of 4 on the scale.
Ruby, a variety of the mineral corundum, has a hardness of 9 on the Mohs scale of mineral hardness.
Gypsum is the mineral listed at 2 on the Mohs hardness scale.
The Mohs scale is used to determine the relative hardness of minerals.
The hardest mineral is diamond, which has a hardness of 10 on the Mohs scale.

This scale was proposed by the Austrian geologist Friderich Mohs.
Minerals have a fairly specific range of hardness, based on the Mohs hardness scale. The Mohs scale is based on the ability of a mineral to be scratched, or scratch, another mineral. Using the Mohs scale to determine mineral hardness is one test that can be used to help identify one mineral from others.
Galena is listed at 2.5 on the Mohs scale of mineral hardness.
He originally came up with the scale when classifying a private collection. He classified them by their physical characteristics rather than their chemical composition, using their relative hardness.
Diamond, with a hardness of 10 on the Mohs scale.
