What are Cubic Monoclinic Triclinic Hexagonal Orthorhombic Tetragonal used for?
Cubic, monoclinic, triclinic, hexagonal, orthorhombic, and tetragonal are crystal systems that describe the geometric arrangements of atoms in crystalline materials. These classifications are essential in materials science, mineralogy, and solid-state physics, as they help in understanding the properties, behaviors, and potential applications of substances. Each crystal system can influence characteristics such as symmetry, stability, and how materials interact with light and other forces, impacting their use in electronics, optics, and structural applications. For example, cubic crystals are often found in metals and salts, while hexagonal crystals are common in minerals like quartz.
What are different class of crystals?
Minerals crystals are divided into six systems depending on the relationships of length of axes and angles between axes. The six mineral crystal systems are: cubic, hexagonal, trigonal, tetragonal, orthorhombic, triclinic, and monoclinic.
Is apatite a rock?
No, apatite is the name of a group of minerals that are hexagonal, trigonal, and monoclinic phosphates, arsenates and vanadates.
Is apatite a sedimentary rock'?
No, apatite is the name of a group of minerals that are hexagonal, trigonal, and monoclinic phosphates, arsenates and vanadates.
3. Which crystal structure do the majority of minerals have?
The majority of minerals crystallize in one of seven primary crystal systems: cubic, tetragonal, orthorhombic, hexagonal, trigonal, monoclinic, or triclinic. Among these, the isometric or cubic structure is particularly common, as seen in minerals like halite and pyrite. However, silicate minerals, which dominate the Earth's crust, often exhibit more complex structures, such as tetrahedral arrangements. Overall, the specific crystal structure of a mineral greatly influences its properties and classification.
How many types of crystals present?
The problem is that "types" is not a well-defined word in the contest of this problem. Do you mean morphology, lattice system, space group, or what? There are more or less infinitely many possible morphologies (I'm pretty sure, though I wouldn't necessarily want to try to prove it, that it's a countable infinity). There are 7 lattice systems: triclinic, monoclinic, orthorhombic, rhombohedral, tetragonal, hexagonal, and cubic. There are 230 distinct space groups, and no I'm not going to list them. Get a graduate-level chemistry book on X-ray crystallography if you really want the details.
What are four main characteristics in minerals that mineralogists look for while examining them?
The color left on a streak plate when the mineral is scratched on the surface of the plate. Different minerals have different streak colors. The mineral is tested for hardness to see where it lies on the Mohs scale. The crystal structure (othorhombic, tetragonal, triclinic, isometric, monoclinic, or trigonal), will help identify the mineral. Different minerals have different densities and weights.

What is a 7th grade answer for how crystals of minerals are classified?
Crystals of minerals are classified based on their chemical composition and internal structure. The arrangement of atoms in a crystal determines its shape and properties. Common classifications include cubic, hexagonal, and monoclinic structures.
What type of structure do minerals have?
Minerals have a crystalline structure, meaning their atoms are arranged in an orderly and repeating pattern. This geometric arrangement can result in various crystal shapes, such as cubic, hexagonal, or tetragonal. The specific arrangement of atoms influences the mineral's physical properties, including hardness, cleavage, and color. Additionally, minerals can be classified based on their chemical composition and crystal system.
What are the two examples of a hexagonal system?
Vanadinite and molybdenite are two minerals that are categorized in the hexagonal crystal system.
Are minerals that have particles arranged in a diamond or crystal pattern?
Atoms within a mineral are arranged into an orderly geometric spatial arrangement known as crystal structure. There are 14 basic crystal lattices (refered to as the Bravais lattices) which fit into one of 7 crystal system (triclinic, monoclinic, orthorhombic, tetragonal, rhombohedral, hexagonal and cubic) and all observed minerals fit into one crystal lattice and one crystal system. Diamond on the other hand is an allotrope of carbon arranged into an isometric hexoctahedral (Cubic-type) crystal system.
