Expected Questions on Science and Technology: UPSC IAS 2017

Dr. Manishika Jain in this video covers a variety of topics which are important for 2017. These include the expected questions on science and technology.

4 New Elements

  • Elements 113, 115, 117 and 118: nihonium, moscovium, tennessine and oganesson
  • Superheavy, radioactive elements will replace the seventh row’s ununtrium, ununpentium, ununseptium and ununoctium
  • Moscovium (Mc) – Moscow
  • Tennessine (Ts) – Tennessee state where Oak Ridge National Laboratory
  • Oganesson: (Og) - for Yuri ganessian helped discover several superheavy elements.
  • 2nd element is named for a living person – 1st time was element 106, seaborgium, named for Glenn T. Seaborg
