Crystals can be elements (as diamond) or compounds (as sapphire).
Crystals can be elements (as diamond) or compounds (as sapphire).
Crystals are the result of a chemical reaction of multiple elements and/or compounds.
Dark purple crystals could indicate the presence of elements such as manganese, iodine, or potassium in their compounds. The color of crystals is often determined by the electronic structure of the element and the way it absorbs and reflects light. Additional tests or analysis would be needed to determine the exact element present in the crystals.
Kind of a tricky question, its best broken into the 2 different ways that the word crystal is used. Crystal can refer to the structure that a compound adopts, there are many different types, the most well known being the structure of salt with what crystallographers call a face centered cubic structure. It is also common to see in reports etc... on the synthesis of organic compounds to say a compound gives white crystals. It is not correct however to assume that crystals that look similar to the naked eye are indeed the same compound, or that all compounds have a crystalline form.
Chemical compounds are formed from chemical elements.
No, crystals are chemical compounds that are not considered to be alive.
There are many different compounds that can form crystals with water, such as salt (sodium chloride), sugar (sucrose), and alum (potassium aluminum sulfate). These compounds can form crystals with water molecules through processes like evaporation or cooling.
Elements and compounds
Many inorganic or organic compounds form crystals.
Elements become compounds after chemical reactions.
