What are some Crystalline elements?

Question

??

Answer 1

Carbon- diamond crystal, graphite is crystalline

Silicon- forms crystals (single crystal Si is used in electronics)
Gallium, Arsenic as well.

Metals form crystalline structures too. You can get x-ray diffraction patterns from metal crystals. Titanium, Scandium, Yttrium, Iron, Copper, Platinum, Nickle, etc.

Answer 2

Almost every element can form crystals in its solid state. Some elements have multiple crystalline state, carbon being the best known. But there are also some elements that also from amorphous forms as well as crystalline. Sulfur is a prime example.

Perhaps you are really asking what elements form crystalline structures at room temperature? Pretty much any element that is a solid at room temperature would do that.

Or perhaps you are asking what elements form pure crystals in nature. That would include copper, silver, carbon, sulfur, and quite a few more. But most of the non-precious metals would be oxidized so would not form pure crystals of only the elemtent.

I have never heard of the noble gases forming crystals in their solid states. But they only have solid states at very low temperatures.

Answer 3

Do you speaks portuguese? If yes, you will understand.
Cristais são estruturas que obedecem a um arranjo tridimensional. É como se os átomos ou moléculas formassem fila em todas as direções. É a forma mais estável de um sólido.

Answer 4

gemstones, such as diamonds and rubies, and silicon wafers used in computers, just to name a few

Answer 5

carbon
