What is the difference between a crystal and luster?
A crystal refers to a solid material with a specific repeating atomic structure, typically with flat surfaces and geometric shapes. Luster, on the other hand, refers to the shine or reflective quality of a surface, which can be metallic, glassy, or dull. In summary, crystals describe a material's structure, while luster describes its appearance.
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 the relationship between a mineral and a crystal, and how do they differ in terms of their composition and structure?
A mineral is a naturally occurring inorganic substance with a specific chemical composition and physical properties. A crystal is a solid material with a repeating geometric pattern. All crystals are minerals, but not all minerals are crystals. Minerals can exist in both crystalline and non-crystalline forms. Crystals have a more ordered and symmetrical structure compared to minerals, which can have a variety of structures.
What do symmetrical crystal shapes indicate about a mineral?
Symmetrical crystal shapes indicate that the mineral has a well-defined crystal structure with uniform internal arrangement of atoms or molecules. This suggests that the mineral formed under conditions that allowed for ordered growth, resulting in distinct geometric shapes.
Are crystals minerals?
Both. Rocks are made of minerals.

What type of orderly structure does a mineral have?
Minerals exhibit a crystalline structure, characterized by a highly ordered arrangement of atoms. This orderly pattern forms a repeating three-dimensional lattice that defines the mineral's specific geometric shape and properties. The arrangement of atoms within the crystal lattice influences the mineral's physical characteristics, such as hardness, cleavage, and optical properties. Each mineral has a unique crystal structure that distinguishes it from others.

What is a solid in which the basic unit is packed in an ordered repeating pattern.?
A crystal is a solid in which the basic unit is packed in an ordered repeating pattern. The arrangement of atoms in a crystal lattice creates a three-dimensional structure with a regular geometric shape. This ordered structure gives crystals their characteristic properties such as transparency, cleavage, and specific melting points.
What distinguishes minerals from other types of solids?
Minerals have a specific chemical composition and an ordered atomic arrangement that differentiates them from other types of solids. They are naturally occurring, inorganic substances that have characteristic physical properties such as hardness, color, and crystal structure. Minerals play a fundamental role in Earth's geology and are essential for various industrial processes and everyday products.
What is an orderly 3-dimensional arrangement formed by atoms or ions called?
An orderly pattern of ions or atoms in a solid is a crystal.
What are 5 criteria that all minerals possess?
Naturally occurring: Minerals must form through natural geological processes. Inorganic: Minerals are not produced by living organisms. Solid: Minerals exist in a solid-state at standard temperature and pressure. Definite chemical composition: Minerals are composed of specific elements in a fixed ratio. Crystalline structure: Minerals have an ordered internal atomic arrangement forming a crystal lattice.
What is the name given to a regular arrangement of particles in a crystalline solid?
Crystal lattice. lattice

Is opal a crystal?
Opal is not classified as a true crystal; instead, it is a mineraloid. Unlike crystals, which have a defined and ordered atomic structure, opal has a more irregular arrangement of silica spheres. This unique structure contributes to its characteristic play-of-color, making opal a popular gemstone despite its non-crystalline nature.
Is glass a crystal?
Glass is not considered a true crystal; it is an amorphous solid, meaning it lacks a well-defined, repeating atomic structure. In contrast, crystals have a regular, ordered arrangement of atoms. While glass can exhibit some properties of crystals, such as clarity and brittleness, its disordered structure distinguishes it from crystalline materials.
Why are minerals considered to be crystalline?
Minerals are by definition occurring in nature, solid, having a specific chemical formula, and having a crystalline structure. When minerals form from a gaseous or liquid state of matter into a solid, their combinations of atoms arrange themselves into a crystalline structure, for example, a quart crystal. These crystalline structures are divided into six or seven (depending on what article you read) crystal systems by length and relationships between the crystal axes.
