The property is hardness.
The hardness, density, and crystal structure.
Yes it is, along with color, streak, luster, density, and hardness.
The Mohs scale is used to identify the mineral property of hardness only.
nothing
They are found in thick layers of rock that squeeze carbon atoms into tight strong crystal. :]
You can use hardness(Moh's Hardness Scale), luster, shape, and fracture to identify quartz.
There are many different materials which can be described as crystal, and they do not all have the same hardness, but in general, no, you cannot cut crystal with a knife.
salt crystal is a pure substance hope this helps xx
physical properties like melting and boiling points, hardness, crystal lattice of ionic substances, density, atomic weight, colour, elasticity, magnetism etc.
a crystal is solid substance which consist of no. of unit cells
1.Color 2.Luster 3.Crystal Shape 4.Flourscent 5.Hardness 6.Density
the piezo-eletric property of a crystal is the principle of quartz clock
