An element ‘X’ contains 6 electrons in ‘M’ shell as valence electrons:

  • What is the atomic number of ‘X’?
  • Identify whether ‘X’ is a metal or non-metal.

Answer:

  • If‘X’ contains 6 electrons in ‘M’ shell as valence electrons, then the electronic configuration of‘X’
    is K = 2, L = 8, M = 6
    Atomic number = 16
  • ‘X’ is a non-metal
