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.
The mineral that would scratch apatite but not scratch fluorite is quartz. Quartz has a hardness of 7 on the Mohs scale, while apatite has a hardness of 5 and fluorite has a hardness of 4. Therefore, quartz can scratch apatite but is too hard to be scratched by fluorite.
Fluorite, which has a hardness of 4 on the Mohs Hardness Scale, can scratch calcite (hardness 3) but will not scratch apatite (hardness 5). Thus, fluorite fits the criteria of being able to scratch calcite while not being able to scratch apatite.
No, a 2p coin is unlikely to scratch apatite and orthoclase as these minerals have a higher hardness on the Mohs scale compared to the coin. Apatite has a hardness of 5 on the Mohs scale, while orthoclase has a hardness of 6-6.5, higher than the 2p coin.
apatite will not scratch quartz topaz calcite or corundum
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.
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.
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.
Yes, fluorite can scratch apatite. Fluorite is harder than apatite on the Mohs scale, which means it has the ability to scratch apatite.
Any mineral with a Mohs hardness of 3 or above. Diamond, for instance.
True
No, a 2p coin is unlikely to scratch apatite and orthoclase as these minerals have a higher hardness on the Mohs scale compared to the coin. Apatite has a hardness of 5 on the Mohs scale, while orthoclase has a hardness of 6-6.5, higher than the 2p coin.
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.
Yes.Apatite - Ca5(PO4)3OH - has a Mohs hardness of 5.Calcite - CaCO3 - has a Mohs hardness of 5.
Apatite is a group of phosphate minerals that are often used in the production of fertilizers, as gemstones, and for industrial purposes. It is found in various colors and is a common mineral in igneous, metamorphic, and sedimentary rocks.

No, apatite is the name of a group of minerals that are hexagonal, trigonal, and monoclinic phosphates, arsenates and vanadates.
