The hardness of a mineral results from the type of chemical bond that exists in that mineral. Bonds vary according to the different elements involved, as well as the particular way in which those elements are combined. It's complicated.

∙ 13y agoThe arrangement and the size of the atoms and ions determines a minerals hardness. Eg.:
1) The highly uniform arrangement of diamond's atoms make it the hardest mineral known, while the same element, carbon, with a sheet-like atomic structure, is one of the softest minerals, called graphite.
2) Larger ions make the carbonates softer than the silicates.

What are facts for hardness?
hardness define minerals
What scale is used to rank the hardness or softness of minerals?
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
The standard scale against which the hardness of minerals is rated?
Mohs hardness scale
What is the difference between a minerals hardness and streak?
A minerals hardness is the ability to scratch or be scratched by other minerals and streak is the colored powder of a mineral that comes off when being scratched.
What is the scratch table of rocks and minerals?
The scratch table is called the Mohs Scale of Mineral Hardness and measures the hardness of minerals in relation to the known hardest (diamond) and softest (talc) minerals.

The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
What does the Mohs hardness scale determine?
The hardness of MINERALS.
What property of minerals is classified by the Mohs scale?
Relative hardness is the property of minerals that uses the Mohs scale for classification.
What is the word used to describe the relative hardness of minerals?
The Mohs Scale is what is used to measure the relative hardness, or scratch resistance, of minerals. Mohs hardness often agrees with absolute hardness, which is another way of measuring the relative hardness of minerals.
How do minerals contribute to the hardness of rocks?
Some minerals have varying hardness according to the direction you may scratch
Hardness of minerals?

What is the scale for the Mohs hardness scale?
Granite is not assigned a number on the Mohs scale of hardness. The Mohs scale is a measurement of the relative hardness of minerals. Because granite is a rock composed of a variety of minerals, only the individual minerals which compose it have a Mohs hardness.
The standard scale against which the hardness of minerals is rated?
Mohs hardness scale
A minerals hardness with respect to other minerals can be determined by?
scratching the mineral acrros a glass plate
What is the difference between a minerals hardness and streak?
A minerals hardness is the ability to scratch or be scratched by other minerals and streak is the colored powder of a mineral that comes off when being scratched.
How many minerals are represented on the Mobs scale of mineral hardness. What is the range of hardness of thoses minerals?
Ten are represented and the scale is from 1-10.
