Diamond is pure carbon, except for occasionally trace minerals that give it colour. Nitrogen is the most common element, giving gem-stone diamonds a yellow cast.
Pure substance; it is one form of pure carbon.
A diamond is mainly carbon in an sp4 crystalline configuration.
Diamond is not a solution in the typical sense. It is a crystalline form of carbon, not a homogeneous mixture of substances like a solution.
No. Diamond is a hard mineral, the hardest natural mineral on earth.
Diamond is a substance (technically, in practice diamonds will have some amount of impurities, so technically they're mixtures, but we'll ignore that). The fact that it's in "chip form" doesn't make any difference.
Pure substance; it is one form of pure carbon.
A diamond is mainly carbon in an sp4 crystalline configuration.
Diamond is a particular elemental compound composed of carbon.
Diamond is a particular elemental compound composed of carbon.
No, a diamond is a form of Carbon which is an element.
No, diamonds are pure diamond, not a mixture of anything.
Pure substance; it is one form of pure carbon.
It's a production of the element carbon, but it itself isn't an element. Some say its a mixture because other minerals other than carbon can influence a diamond's colour.
Technically, diamond is neither an element, a compound, or a mixture. Diamond is made up of pure carbon atoms, so it is not a mixture, and a compound by definition requires two or more different elements. The best definition using the above terms is that diamond is a mineral made up of the same element.
Crystals can be elements (as diamond) or compounds (as sapphire).
Iodine crystals can be separated from diamond by using sublimation. Iodine can be sublimated at a low temperature, converting it from a solid to a gas without melting. This allows the iodine to be collected as a gas, leaving behind the diamond.
Pure diamond is unique in that it is a gemstone composed of a single element, carbon. However, most white diamonds contain trace amounts of nitrogen, with less than 2% of natural white diamonds having no nitrogen. So, speaking of pure diamond, it is not a mixture, but in reality, most white diamonds do contain trace impurities of nitrogen (less than 1% however).
