Gold is found in free State but iron is not?give reason
Answers
Answer:
Gold is a non reactive metal . ... It can form compounds more easily and is hence placed above hydrogen in the reactivity series.It is mostly found in the form of iron oxide after reacting with oxygen and water . So , Gold is found in free state but iron is not.
I hope my answer is helpful for you
Thank you
Answer:
Gold is made from a compund which can be formed more easily and it is placed above hydrogen in the reactivity series and hence it is non reactive metal.
Explanation:
Gold is a precious metal and does not easily react with other elements and form compounds. Therefore, gold is found naturally as a free metal. On the other hand, iron is not naturally found in the free metallic form because it is stable after the oxide is formed. Metals that are not detected in the free state depend on their reactivity. Some highly reactive metals are found in bound form, such as sodium. On the other hand, precious and less reactive metals such as gold and silver are found in the free state and are not chemically bound to matter. Note that physical impurities do not bond metals.
