Define (i) mineral (ii) ore.Aluminum occurs in combined state whereas gold is found in free state in nature. Why? |
|
Answer» The elements or compounds which occur naturally in the earth's crust are known as minerals. The mineral from which a particular metal can be profitably extracted is called ore. Gold is very less reactive whereas aluminium is a very reactive element. Therefore, aluminium reacts with other elements or compounds more than gold. Thus, aluminium occurs in combined state while gold occurs in free state |
