Why can planning be use to obtain the element gold but cannot be use to obtain the element iron?
I think the word you seek is Panning, not Planning. Gold, when found as a fairly pure metal, can be separated from rock/sand by panning or a sluice box due to the much greater weight of gold. However, iron is rarely found as a pure metal, but as an ore that must be refined to get iron. The iron is chemically combined with something else, such as oxygen.
Iron is a pure metal or alloy?
Iron is a pure metal.
Why a pure metal half immersed vertically in water starts corroding?
It is a reaction with oxygen (from the air or dissolved in water).
At what temperature does metal burn?
To burn iron, the temperature needs to be more than 1200 degrees Celsius. The metal must be white hot and surrounded by pure oxygen to burn up.
Can gold burn?
Pure gold is a noble metal and does not combine readily with anything. It is inert in an oxygen atmosphere and will not burn.
What is the word for removing oxygen from metals?
Either deoxidation or reduction would be a suitable word. However, note that from a pure metal, oxygen can not be removed, because none is present.
What happens when making metal?
You can not actually make metal but you can obtain metal from an ore of that metal. The ore is a chemical compound of that metal and the process of smelting the ore involvesf breaking the compound up using heat and "reducing it" essentially removing oxygen - to leave the pure metal.

Iron is a pure metal.
What happens when metals react with pure gas?
If the gas is oxygen, the oxide of the metal is most likely to form.
What happens if you don't get enough oxygen in your diet?
We obtain oxygen by breathing, not by eating. Oxygen does not have to be present in the diet, at least, not in pure form. The compounds that make up our food do include oxygen. That is unavoidable. If you eat anything other than pure salt, there is oxygen in the molecules that you are eating. Water contains oxygen as well (H2O, two hydrogen and one oxygen).
Do you need to separate any matirials to get thorium?
To obtain pure thorium metal it is necessary to separate thorium from other elements.
Is alloy or a pure metal?
pure metal

How is potassium stored?
The pure metal must be stored under oil to protect it from oxygen and water vapor in the air.
How are redox reactions used to obtain pure metals?
One way is electrolytic reduction of metal cations from molten salts. Another is heating with carbon, which can reduce the metal ions in many metal oxides to elemental metal atoms.
Is oxygen pure or a mixture?
Oxygen is an element and a pure substance.
