Is mineral luster classified as being metallic or opaque?
Mineral luster is broadly classified as metallic or non-metallic.
Is diamond a translucent material?
Gem-quality diamonds can be said to be transparent to translucent in rough crystals. Industrial diamonds are cloudy -- intensely flawed -- and may be opaque, but are not considered transparent.
Why do you use transparent mixing toners for metallic colors?
Transparent mixing toners are used for metallic colors because they maintain the reflective properties of metallic pigments while allowing the color to remain vibrant and true. Adding opaque colors to metallic paints can dull the metallic effect, so using transparent toners ensures that the metallic sheen is maintained.
Why graphite is opaque and diamond is transperent?
Different physical structures. Both are pure (or nearly so) carbon. Graphite is a powder made of tiny flakes, while diamond is a rigid crystal.
How do you compare and contrast the shapes of the samples of halite and quartz?
Halite typically forms cubic crystals with smooth faces, while quartz forms hexagonal prisms with pointed ends. Halite crystals are transparent and colorless, while quartz crystals can vary in color and are often translucent or opaque. Additionally, halite has a salty taste and is softer than quartz, which is a hard mineral.
What is the lustre of phosphorus?
Phosphorus typically has a waxy appearance with a slight metallic sheen in its white form. Yellow phosphorus is opaque and resinous-looking, while red phosphorus appears dull and powdery.
What are the key differences between the properties of diamond and graphite?
Diamond and graphite are both forms of carbon, but they have different properties. Diamond is a hard, transparent crystal with a high melting point, while graphite is a soft, opaque material with a lower melting point. Diamond has a three-dimensional structure, making it hard and durable, while graphite has a layered structure, allowing it to be used as a lubricant.
Gemstones are translucent or opaque?
Yes. Diamond is made of carbon, and many plastics also contain carbon. Polystryene, polycarbonate and many other plastics are also transparent, while mercury (a liquid) is not. It's to do with the atomic/ molecular structure, and whether the molecular structure allows light transmission.
What is the apearrance of unheated sulfur and iron filings?
Sulfur is a fine powder that is light yellow in color; iron filings are metallic. A mixture would be just that: a light yellow powder intersperced with metallic particles.
Is earth made of diamond?
No, the Earth is not made of diamond. Diamond is a specific form of carbon crystals that are created under high pressure and temperature conditions, while the Earth's composition is mostly made up of silicate minerals and a small percentage of metals like iron and nickel.
What are the key differences between graphite and diamond in terms of their physical properties and uses?
Graphite and diamond are both forms of carbon, but they have different physical properties and uses. Graphite is soft, opaque, and a good conductor of electricity, while diamond is hard, transparent, and a poor conductor of electricity. Graphite is commonly used in pencils, lubricants, and electrodes, while diamond is used in jewelry, cutting tools, and industrial applications requiring hardness and durability.
Can crystals ever be made out of covalent bonds or is it strictlly only ionic?
Crystals can be made from covalent bonds as well as ionic bonds. Covalent crystals are formed when atoms share electrons, creating a network of interconnected atoms with strong directional bonds. Diamond and quartz are examples of covalent crystals, while sodium chloride (salt) is an example of an ionic crystal.
