    Answer: Diamond

    Diamonds are the hardest natural substance on Earth. Diamond crystals are brought closer to the earth’s surface through volcanic activity. Diamonds are colorless, in their pure state. Blue and red are the rarest colored diamonds. Yellow and brown are the most common colored diamonds. Diamond were first discovered in India, Until the 18th century, the only diamond mines were in India.

    The largest diamond ever found was the Cullinan at 3106 carats.
    Diamonds can only be scratched by other diamonds.

    Copper is a chemical element with the symbol Cu and an atomic number 29.  Copper is the only metal than gold and cesium to have a natural color than grey. Copper has a pink color. You know that Copper comes second in the list of metals with the highest electrical conductivity.

    RE: Odd one out


    Symbol: Cu
    Atomic Number: 29
    Atomic weight: 63.546
    Classification: Transition metal
    Phase at Room Temperature: Solid
    Density: 8.96 grams per cm cubed
    Melting Point: 1084 C, 1984 F
    Boiling Point: 2562 C, 4644 F

    Lead is an interesting element that we use everyday. Lead is used to refer to the black core of pencils, even though it does not content the element lead. It does not occur in nature in large amount. It is usually found in zinc, silver and copper ores.  Today, over half of the lead produced is used as electrodes in lead-acid car batteries.

    Atomic Number: 82
    Atomic Symbol: Pb
    Atomic Weight: 207.2
    Melting Point: 621.4 F (327.46 C)
    Boiling Point: 3,180.2 (1749 C)

    Silver is the highly valuable metal is slightly harder than gold and has the highest electrical conductivity of any of the metals.  You know, In a dozen or more languages, the words ‘money’ and ‘silver’ are the same.
    There was 17,40,000 metric tons of silver discovered in the world up to the year 2007.
    Silver has been coined to use as money since 700 BC.
    Mirrors are coated with silver because it reflects nearly all light.
    In India, food can be found decorated with a thin layer of silver, known as varak.
