Which object can scratch apatite but not feldspar?
Diamond can scratch apatite but not feldspar. This is due to the difference in hardness between the two minerals, with diamond being the hardest natural substance on the Mohs scale at 10, while apatite is around 5 and feldspar is around 6-6.5.
Can fluorite scratch apatite?
Yes, fluorite can scratch apatite. Fluorite is harder than apatite on the Mohs scale, which means it has the ability to scratch apatite.
Is this statement true or false that apatite can scratch calcite?
Yes.Apatite - Ca5(PO4)3OH - has a Mohs hardness of 5.Calcite - CaCO3 - has a Mohs hardness of 5.
What hardness does a mineral have if it does not scratch glass but scratches an iron nail?
The mineral would have a hardness between 5.5 and 6.5 on the Mohs scale. It cannot scratch glass (hardness of about 5.5) but can scratch an iron nail (hardness of about 4). This places it in the range of minerals like orthoclase feldspar or apatite.
Which mineral would scratch calcite but not apatite?
Fluorite would be able to scratch calcite but not apatite, as fluorite has a higher hardness than calcite but a lower hardness than apatite on the Mohs scale.

Can fluorite scratch apatite?
Yes, fluorite can scratch apatite. Fluorite is harder than apatite on the Mohs scale, which means it has the ability to scratch apatite.
Which minerals can scratch apatite?
Minerals that can scratch apatite include fluorite, quartz, topaz, and corundum. These minerals have a higher hardness level than apatite on the Mohs scale, which allows them to scratch apatite.
Which mineral on the mohs scale will scratch apatite?
Minerals that will scratch apatite must be more than a 5 on the Moh's hardness scale. So feldspar, quartz, topaz, corundum, and diamond will scratch apatite.
Can a 2p coin scratch apatite?
No, a 2p coin cannot scratch apatite. Apatite is composed of calcium phosphate minerals which are harder than the metal used in a 2p coin.
Can Apatite can scratch calcite?
True
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.
Is this statement true or false that apatite can scratch calcite?
Yes.Apatite - Ca5(PO4)3OH - has a Mohs hardness of 5.Calcite - CaCO3 - has a Mohs hardness of 5.
Which mineral will not scratch quartz topaz calcite or corundum?
apatite will not scratch quartz topaz calcite or corundum
Can the mineral azurite scratch glass?
apatite can not scratch glass. it is considered number 5 1/2 on the Mohs Scale Of Hardness. Apatite is number 5 on the scale and can only scratch itself and all of the minerals lower on the scale.
