Facts

Interesting Facts
  • At room temperature mercury is found in a liquid state.
  • A coin of pound or rupees floats in mercury.
  • Because of its low melting point and boiling point it is used in thermometers.
  
  • The most stable isotope of Nobelium metal is No-259.
  • No-259 has a half-life of fifty-eight minutes.
