Question
Two elements X and Y have atomic numbers 12 and 16 respectively. Write the electronic configuration for these elements. To which period of the Modern Periodic Table do these two elements belong? What type of bond will be formed between them and why?
✓

Answer

  • Electronic configuration of x- 2, 8, 2.
  • Electronic configuration of y- 2, 8, 6.
  • X- Period 2 and Group 2.
  • Y- Period 2 and Group 16.
  • Thus X is Metal and Y is non metal.
  • So they formed Ionic Bond.
