I don't found the Mohs hardness of plutonium but: - the Brinell hardness is 242 at r.m. - the Vickers hardness is 255 at r.m. After a hardness conversion chart an equivalent Mohs hardness may be 3,7.
It's called the Ore
it is 6 1/2 in the mohs hardness scale
Mohs 3.5-4.0.
Mohs 3.5-4.0.
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
The Mohs hardness of sodium chloride is 2,5. The Mohs hardness is established by comparison with other minerals, having a known hardness.
