No one seems to know how hard scandium is on the mohs hardness scale (believe me i looked everywhere and they all say N/A) but i did manage to find it's hardness on the Brinell hardness scale. On the Brinell hardness scale it is 750 MPa. If you find how hard it is on the mohs scale please revise my awnser to also include that.

Is feldspar harder than calcite?
no,calcite is ranked number 3 on the mohs scale of hardness. topaz is ranked number 8 on mohs scale of hardness. 10 is the hardest(diamond) 1 is the softest(talc) look it up!
What is the name of the mineral hardness scale?
It's called the Ore
Which minerals on Mohs' hardness scale can be scratched by quartz?
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
What is fluorite on the mohs hardness scale?
Fluorite is the number 4 mineral on the Mohs scale of mineral hardness, above calcite and below apatite.
Is fluorite harder than calcite?
The mineral fluorite is harder than calcite. Fluorite is represented as a 4 on the Mohs scale of relative mineral hardness, calcite is a 3.
What will scratch calcite?
Using the Mohs Mineral Hardness scale, calcite has a hardness of 3. Hence anything with a hardness of 3 or above can scratch calcite (i.e...quartz and fluorite).
How do you identify the property of a mineral but what does it mean where we say calcite has a hardness?
We use Mohs scale of mineral hardness to access the hardness of minerals, which calcite is one example.
Is feldspar harder than calcite?
no,calcite is ranked number 3 on the mohs scale of hardness. topaz is ranked number 8 on mohs scale of hardness. 10 is the hardest(diamond) 1 is the softest(talc) look it up!
What can scratch calcite?
calcite is a 3 on the Mohs scale of Hardness and can scratch anything that's under it. just that simple
What is the name of the mineral hardness scale?
It's called the Ore
Which minerals on Mohs' hardness scale can be scratched by quartz?
Othoclase, apatite, fluorite, calcite, gypsum, and talc.
What scale is used to find a mineral's hardness?
the mohs hardness scale
What is fluorite on the mohs hardness scale?
Fluorite is the number 4 mineral on the Mohs scale of mineral hardness, above calcite and below apatite.
Is fluorite harder than calcite?
The mineral fluorite is harder than calcite. Fluorite is represented as a 4 on the Mohs scale of relative mineral hardness, calcite is a 3.
If a mineral scratches calcite but is scratched by apatite what is the minerals hardness?
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
Which object can scratch calcite but not apatite?
On the Mohs mineral hardness scale, calcite is about a 3, and apatite is about a 5. So, whatever is at a hardness of 4 will scratch a 3 but not a 5. That mineral is fluorite.
What is the hardness of diatomite on the mohs scale of hardness?
