Correct Answer - Option 5 : Mercury

The correct answer is Mercury.

  • Cinnabar is a toxic ore of Mercury.
    • The chemical formula of Cinnabar is HgS.
    • It is the bright scarlet to the brick-red form of mercury(II) sulfide.
    • It is the most common source of ore for refining elemental mercury.
    • It is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments.
  • Mercury is a chemical element with the symbol Hg and atomic number 80.
    • It is commonly known as quicksilver and was formerly named hydrargyrum.
  • Hence, option 3 is correct.

  • Lead :
    • Lead is a chemical element with the symbol Pb and atomic number 82.
    • It is a heavy metal that is denser than most common materials.
    • Lead is soft and malleable, and also has a relatively low melting point.
    • When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull grey colour when exposed to air.
  • Iron :
    • Iron is a chemical element with the symbol Fe and atomic number 26.
    • It is a metal that belongs to the first transition series and group 8 of the periodic table.
    • It is by mass the most common element on Earth, right in front of oxygen, forming much of Earth's outer and inner core.
    • Iron is a mineral that the body needs for growth and development.
    • Your body uses iron to make haemoglobin, a protein in red blood cells that carries oxygen from the lungs to all parts of the body.
  • Copper :
    • Copper is a chemical element with the symbol Cu and atomic number 29.
    • It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity.
    • A freshly exposed surface of pure copper has a pinkish-orange colour. 
  • Silver :
    • Silver is a chemical element with the symbol Ag and atomic number 47.
    • Silver ( Ag ) is a white, soft, lustrous, very ductile, and malleable metal.
    • It is a very good conductor of electricity and heat.
    • It has the highest electrical conductivity of all metals, but the high cost of it has restricted us from using it in all electrical devices.
