FCC crystal structure has 12 slip planes because of its cubic symmetry, which allows slip to occur in many directions. HCP crystal structure, on the other hand, has 3 slip planes due to its hexagonal close-packed arrangement, which restricts the slip to fewer directions.
Pyroxenes have a single chain structure, while amphiboles have a double chain structure. Pyroxenes typically have a simpler, more elongated crystal structure compared to the more complex, ribbony structure of amphiboles. Additionally, pyroxenes commonly have a monoclinic or orthorhombic crystal system, while amphiboles have a monoclinic system.
Yes, I found out that the less color a crystal has the more it will grow.
An antifluorite is a type of crystal structure in which the cations and anions in a crystal lattice are arranged in a specific pattern. In an antifluorite structure, the anions occupy the positions that cations would normally occupy, and vice versa. This results in a reversed or "anti" arrangement compared to the more common structure of fluorite.
The type of crystal structure doesn't affect the transparency. For example a body centered cubic structure is no more and no less transparent than a hexagonal close packed structure. However if the block of substance is a mess of many crystal structures stuck together in no coherent order then yes it does affect the transparency.Transparency is more dependent on the chemical bonds and the particular light that they absorb. These bond energies are unaffected (ok maybe slightly affected) by the particular crystal structure they find themselves in.Crystal structure however does have a big influence on the index of refraction of light. You can have left refraction, right refration or even both at the same time depending on the crystal structure.
A crystal system is a method for categorizing minerals based on their crystal structure and symmetry. This classification is useful because it helps geologists and mineralogists identify and describe minerals more accurately. It also provides insight into the physical properties and formation conditions of minerals within each crystal system.
this question need more detail. first of all, a crystal's external appearance is merely a representation of its ordered internal atomic structure. to look at crystal structure in general, I recommend researching the 14 Bravais Lattices. Depending on what crystal you are talking about, its internal atomic structure will be different.

The crystal structure and composition of a mineral are more reliable indicators of its identity compared to color. Color can vary due to impurities or environmental factors, whereas crystal structure and composition are more definitive characteristics that help in identifying minerals accurately.
cools slowly.
According to Wikipedia: The mineral sphalerite... "crystallizes in the cubic crystal system. In the crystal structure, zinc and sulfur atoms are tetrahedrally coordinated. The structure is closely related to the structure of diamond." You can read more about Bravais lattaice by following the link, below.

In unrestricted space, a crystal can grow without any obstacles limiting its expansion in all directions. As the crystal structure forms, atoms or molecules attach to the surface of the crystal in a repeating pattern, gradually building up its structure and size. This process continues until there is no more material available for the crystal to grow.
An antifluorite is a type of crystal structure in which the cations and anions in a crystal lattice are arranged in a specific pattern. In an antifluorite structure, the anions occupy the positions that cations would normally occupy, and vice versa. This results in a reversed or "anti" arrangement compared to the more common structure of fluorite.
Yes, forming a crystal in a restricted space can affect its structure. The limited space may apply pressure on the crystal lattice, causing it to adopt a different arrangement or orientation than it would in a more open environment. This may result in altered physical properties or crystal symmetry compared to a crystal grown in unrestricted conditions.
A face-centered tetragonal crystal structure has unique characteristics such as having a rectangular base with additional atoms at the center of each face. This structure is similar to a simple tetragonal structure but with additional atoms at the face centers, giving it a more symmetrical shape.
A crystal shape refers to the geometric form or structure that a mineral naturally takes on when it solidifies. This can include shapes like cubes, hexagons, prisms, or even more complex forms depending on the mineral's atomic structure and growth conditions.
