What is an antifluorite?
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.
Does the crystalline structure affects the transparency of a material?
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.
What is structure of zinc crystal?
It is a box shape. Here is some more info on the subject matter pertaining to your specific circumstances:Space group: P63/mmc (Space group number: 194)Structure: hcp (hexagonal close-packed)Cell parameters: a: 266.49 pm
What is Differentiate between polymorphism and isomerism?
Polymorphism and Allotropy are same thing. Polymorphism is used for compounds and the allotropy is reserved for elements. You can go for XRD to check the crystal structure and their composition to distinguish.
What is the crystal structure of a sapphire?
Diamond crystals are cubic, and are based on what is called a face centered cubic structure. Each carbon atom is linked to four other carbon atoms in a cube. If you can picture a cube with its six faces, there is a carbon atom at each corner. Additionally, there is a carbon atom in the middle of each square face that is bound to each atom at the corner of the square. Links can be found below for more information.
What does the crystal structure look like?
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.
What is A repeating pattern of atoms ions or molecules in a mineral called?
of crystals.
Bravais lattice structure of diamond and zinc blend?
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.

What is the crystal structure of talc?
The crystalline structure of talc can be monoclinic or triclinic. Monoclinic crystals are rectangular prisms with a parallelogram as the base. Triclinic crystals have no mirror planes and little symmetry. In layman's terms, the crystal structure of talc is pretty irregular and haphazard, giving it a rough appearance.

Is minerals rocks?
No, minerals are not rocks. Minerals are one or more elements stacked together which forms a crystal structure. A rock is composed of one or more minerals.
What are the propertys of a crystal?
There are a number of ways to characterize a crystal. First is its chemistry. Is it an element that takes the form of a crystal, like carbon creates a diamond? Or is it a crystal of a compound like sodium chloride, which is table salt? We need to look at the structure of the crystal to see how the atoms or molecules "arrange" themselves to form the crystal. There is a basic pattern (one of 7 fundamental ones) somewhere and it repeats over and over to form the crystal. This is crystal structure, or lattice parameters. How does light react when it passes through the crystal? There are a number of optical properties we can consider, and just one is refractive index. What is the electron band structure of the crystal? How does it act when we apply a voltage across it or heat it? Does it conduct, and to what degree? There are other characteristics, but this should get you started in a big way. Use the link below for more information.

Is a bowl of sugar a solid liquid or gas?
Sugar is a solid. Look up crystal structure and aldoses and keytoses for more information on sugars and their crystals.
Why gold is more ductile than sodium?
Both gold and sodium are metals. Gold has face centred cubic crystal structure, sodium has body centered cubic structure. A face centred cubic structure allows an easy movement of dislocations in the lattice. Gold is extraordinarily ductile.
