yes
Silver is harder than gold but softer than copper.
Diamond is much harder than copper. On the Mohs hardness scale (higher numbers are harder), diamond is a 10 and copper is somewhere between 3 and 4.
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.
You can distinguish quartz from calcite by conducting a hardness test, as quartz is harder than calcite. Additionally, you can test for effervescence with acid - calcite will fizz in acid while quartz will not react. Lastly, observing the cleavage patterns can also help differentiate the two minerals, as quartz has no cleavage while calcite has rhombohedral cleavage.
Bronze is an alloy made of copper and tin, which forms a crystalline structure that makes it harder than pure copper. The presence of tin in the alloy strengthens the material and alters its properties, including increasing its hardness.
Calcite scratching a copper coin is harder because calcite has a higher Mohs hardness scale rating than copper. Steel files can scratch penknife blades because steel is harder than the blade material, which is usually softer.
Yes, fluorite is harder than calcite. Fluorite has a hardness of 4 on the Mohs scale, while calcite has a hardness of 3. This means that fluorite can scratch calcite, but calcite cannot scratch fluorite.
yes
It can be hard to remember the hardness levels of all the minerals and substances of the Earth. Calcite is something that is harder than gold.Ê

Calcite is a mineral that is harder than gypsum but softer than fluorite on the Mohs scale of mineral hardness. Calcite has a hardness of 3, while gypsum has a hardness of 2 and fluorite has a hardness of 4.
Quartz is much harder than calcite.
Glass is generally harder than calcite. Calcite has a Mohs hardness of 3, while glass typically has a Mohs hardness of around 5.5. This means that glass is more resistant to scratching and abrasion compared to calcite.
Silver is harder than gold but softer than copper.
Quartz because its harder than calcite and the quartz in thicker.
No it is not.
Fluorite and apatite are two minerals that are harder than calcite but softer than quartz on the Mohs scale of mineral hardness. They have hardness values of 4 (fluorite) and 5 (apatite) respectively, compared to 3 for calcite and 7 for quartz.
