Diamond is an extremely stable form of carbon: It is a material with superior physical properties due to the very strong covalent bonding between the carbon atoms. Diamond has the highest hardness and thermal conductivity of any known natural or synthesized material.
What type of rock is a diamond?
igneous rock
Is Diamond a silicate?
The silicate group was subdivided in part on the basis of composition but mainly according to internal structure….
Is gold a silicate?
Many non-silicate minerals are economically important and provide metallic resources such as copper, lead, and iron….3.5: Non-Silicate Minerals.
What are the 6 mineral groups?
Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups.
What is not a native element?
The noble gases include helium, neon, argon, krypton, xenon, and radon. Similarly, diatomic gases, such as hydrogen, oxygen, and nitrogen are not considered native elements.
Is gold a native mineral?
Only gold, silver, copper and the platinum group occur native in large amounts. Over geological time scales, very few metals can resist natural weathering processes like oxidation, so mainly the less reactive metals such as gold and platinum are found as native metals.
What are the 5 native elements?
These native elements are commonly divided into three groups—namely, metals (platinum, iridium, osmium, iron, zinc, tin, gold, silver, copper, mercury, lead, chromium); semimetals (bismuth, antimony, arsenic, tellurium, selenium); and nonmetals (sulfur, carbon).
What metals are pure?
Pure Metals
What is the purest metal on earth?
Platinum Purity Platinum, with its beautiful white luster, is the purest of all the precious metals used for fine jewelry. This grayish white to silver gray metal is harder than gold and very durable with a hardness of 4-4.5 on the Mohs hardness scale, equivalent to the hardness of iron.
What is the most expensive metal in the world?
