    What is a metal ore?

    • A.

      A naturally occurring substance with metallic properties that can be used for industrial purposes.

    • B.

      Any metallic material that is extracted from the Earth's crust.

    • C.

      A mineral deposit composed of valuable metals and non-metallic minerals.

    • D.

      An alloy produced by combining various metals through a smelting process.

    Correct Answer
    A. A naturally occurring substance with metallic properties that can be used for industrial purposes.
    A metal ore is a naturally occurring mineral or rock that contains a high enough concentration of metal elements to be economically extracted and processed. These ores are typically found in the Earth's crust and can be mined for their valuable metal content. They are the primary source of metals such as iron, copper, gold, silver, and aluminum, which are used in various industries and manufacturing processes. Ores are often processed through techniques like crushing, grinding, and smelting to extract the desired metal from the ore minerals.

    Name 2 metals that are easy to find without being joined onto other substances.

  • 5. 

    Tick the most reactive metal.

    • A.


    • B.


    • C.


    • D.


    Correct Answer
    C. Zinc
    Zinc is the most reactive metal among the given options because it readily reacts with other substances, such as acids and oxygen. It can displace hydrogen from acids and oxygen from water, indicating its high reactivity. Platinum, on the other hand, is a noble metal and is known for its inertness and low reactivity. Copper is also less reactive compared to zinc, and hydrogen is not a metal but a nonmetal. Therefore, zinc is the correct answer as the most reactive metal among the given options.
