If a mineral can be scratched by a fingernail but not by a pocket knife what does that tell us about the mineral?
It would have a Mohs hardness somewhere between 2.5 and 5.5.
What is a mineral's ability to scratch another mineral?
A mineral's resistance to being scratched (or when a force is applied) is called its hardness.There are different measurements of hardness: scratch hardness, indentation hardness, and rebound hardness. A material's hardness depends on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity.
Measure of how easily a mineral can be scratched which is determined b the arrangement of of a minerals atom?
This property is known as the hardness of the mineral. It is determined by the strength and arrangement of atoms within the mineral's structure, affecting how easily it can be scratched by other materials. Hardness is measured using the Mohs scale, which ranks minerals from 1 (softest) to 10 (hardest).
What is the harness of a mineral if it scratches a penny but will not scratch glass?
Google "Mohs hardness scale". This is a relative hardness scale which compares one mineral's hardness to another. (It is between 3.5 and 5.5 on the Mohs hardness scale)
Why do you need to know hardness and streak to identify minerals?
Any identifying characteristics help when you are dealing with an unknown mineral. You have to use all of the clues at your disposal to make a proper identification. Streak and hardness are 2 important tests.
Is hardness a reflection of the strength of a mineral bond?
yes it is
If a mineral can be scratched by a fingernail but not by a pocket knife what does that tell us about the mineral?
It would have a Mohs hardness somewhere between 2.5 and 5.5.
What is mineral hardness-?
Is a mineral's ability to resist being scratched, and is defined by its location on the numerical Mohs scale of mineral hardness by a designation of a number between 1 and 10. See the related link on Mohs hardness.
What is the ability of a mineral to hold together?
The ability of a mineral to hold together is known as its hardness. It is a measure of a mineral's resistance to scratching or abrasion. Hardness is determined by the strength of the atomic bonds within the mineral's crystal structure.

What will if you rub a mineral with the hardness of 3 with a mineral with a hardness of 9?
The mineral with hardness 3 will get scratched.
What is the hardness of an unknown mineral that scratches glass but will not scratch quartz?
The unknown mineral would have a hardness greater than 5.5 (the hardness of glass) but less than 7 (the hardness of quartz). Based on the Mohs Hardness Scale, the unknown mineral would likely have a hardness between 6 and 7.
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...
What is the hardness of a mineral if it scratches a penny but will not scratch glass?
Between 3.5 and 5.5 on the Mohs scale of mineral hardness.
Is a Gray mineral harder than a white mineral?
No, there is no correlation between color and hardness in minerals.
What is the hardnessof a mineral that scratches the gypsum but can't scratch fluorite?
Between 2 and 4. Calcite, which has a hardness of 3, is one example.
