What else can I help you with?
Do most minerals occur in a pure form?
no, because they have to be treated become pure.
Which metals are not found in ores?
There are a lot more than five. For example, all the alkali and alkaline earth metals are not found naturally in pure form but occur only in compounds. It's actually unusual for a metal to exist in pure form in nature; most of them occur only in compounds.
What state do almost all metals occur in naturally?
Metals typically occur in their native form, meaning they are found naturally as pure elements in the Earth's crust. This is because metals are stable in their metallic form due to their high reactivity with other elements.
Why are metals like aluminum never found in the Earth as pure metals?
Aluminium is a reactive metal and in nature only the most unreactive metals (such as gold) are found in thir pure form.
Which metals are not very reactive and occur in a free state in nature?
Gold, silver, and platinum are examples of metals that are not very reactive and occur in a free state in nature. These metals are often found in their pure form, which makes them relatively easy to mine and extract.
Does pure substances have a fixed composition?
No. The nobel gases and the rare earth metals (gold, platinum) occur as pure substances in nature because they are relatively unreactive. Most materials do not occur as pure substances (typically oxidized) and must be treated to be made pure.
What happens when metals react with pure gas?
If the gas is oxygen, the oxide of the metal is most likely to form.
Which native metals are found in a pure form?
Gold
Does vanadium occur naturally in it's pure form?
No, it does not exist naturally in its pure form. Itexists in the combined form.
Why are gold and platinum found as pure metals?
Gold and platinum are found as pure metals because they are very unreactive and resistant to corrosion. This allows them to exist in nature in a relatively pure form without reacting with other elements. Additionally, their chemical properties make them highly resistant to oxidation and weathering, further contributing to their presence as pure metals.
Does alkali metals occur freely in nature?
Alkali metals such as sodium and potassium are found in nature in various compounds, but they are not typically found in their pure form. They are highly reactive and readily react with other elements to form compounds.
How do metals in living things compare to the pure form of the metals?
The metals in the living things usually are combined with other elements in chemical compounds.
