Carbon can occur as graphite, which has black crystals.
Colorless Solid
That would be carbon
Pyrite has a cubic crystal structure with metallic luster and a brassy yellow color, while gypsum has a monoclinic crystal structure with a pearly luster and colorless to white appearance. By examining the crystal structure under a microscope and observing the physical properties such as color and luster, one can distinguish between pyrite and gypsum crystals.
Carbon is a black color. It got it's name from the Latin word "carbo" meaning charcoal. The black color of smoke actually comes from unburned specks of carbon.
Elemental carbon can have two different solid phases with differing spatial (position) ... Crystal structures are determined experimentally by X-Ray Diffraction. So the position of the element is determined experimentally by X-ray diffraction of a crystal of the element.
Iodine is an element that can exist as a black solid or colorless crystal.
most bromides are solids but the element bromine is a liquid.
When heated, zinc oxide (white powder) decomposes into zinc vapor (colorless gas) and solid zinc suboxide (black solid).
Colorless Solid
Iodine is a naturally occurring element on the periodic table with the chemical symbol I and atomic number 53. At room temperature, iodine is a solid that appears as a shiny, purple-black, metallic-looking crystal.
Quartz is a solid compound from the earth's crust. Its chemical composition is SiO4 (silicon oxygen tetrahedra), and it has a definite crystal shape.
Solid - all ionic compounds are! (at room temp)
Sodium phosphate is a white crystalline solid that is colorless or appears as a white powder.
Phosphorus is an element that turns white when exposed to air. When pure, it is a colorless and transparent waxy solid.
