Is coal not a mineral because it has a crystal structure?
No. Coal is not a mineral for two reasons: it lacks a crystal structure and it is organic.
What is the crystal shape of agate?
Agate, being a cryptocrystalline (microscopic crystal structure) form of quartz, does not have a crystal shape.
What are some examples of rocks that came from fire?
Granites and basalts.
Why do minerals that have the nonsilicate crystalline structure called closest packing have high density?
Minerals of a nonsilicate crystal have very high densities because their crystal structures are based on the packing of atoms that are as close together as possible. This structure is called this closest packing.
How are desert roses formed?
A desert rose forms when gypsum, calcite, or silica crystals form in loose desert sand. The crystal incorporates the sand grains within its crystal latice and therefore the desert rose looks like it is made of sand yet it retains a crystal structure.
What is the crystal structure for silver?
There is no crystal structure.
Dose malachite have a crystal structure?
Yes, malachite does have a crystal structure. It belongs to the monoclinic crystal system.
What is the crystal structure of beryllium?
Beryllium's crystal structure is hexagonal.
What is the crystal structure of tungsten?
Tungsten's crystal structure is cubic.
What is the crystal structure of fermium?
The crystal structure of fermium was not determined.
What is the crystal structure of phosphorous?
The crystal structure of phosphorous is monoclinic.
What does definite crystal structure mean?
a crystal structure is a turtle in disguise
Why are the crystals in pillows basalts smaller than those in many other examples of basalts?
A factor that determines crystal size in igneous rocks is the speed in which the lava/ magma crystallised or froze. As pillow basalts form at mid ocean ridges where magma is erupted into direct contact with the cold sea water the crystals form very fast and are therefore small. Other basalts erupted on land still have relatively small crystals and crystallised relatively fast but overall slower then pillow basalts.
What is radium's crystal structure?
The crystal structure of radium is cubic, body-centered.
What is the crystal structure for helium?
Crystal structure is for solids and for gases. Helium is a gas and doesn't form any crystal.
What is an an orderly three dimensional arrangement formed by ions called?
a crystal.
What is the crystal structure of fluorine?
The crystal structure of fluorine is a monoclinic structure at normal atmospheric pressure. It forms a lattice of individual F2 molecules arranged in layers.
