Question
Elements belonging to which groups constitute the p-block and why?
✓

Answer

  • Elements belonging to groups 13, 14, 15, 16, 17 and 18 constitute the p-block.
  • The last electron in the p-block elements is filled in p subshell.
  • As p subshell contains three degenerate p orbitals, it can accommodate up to 6 electrons.
  • Therefore, the p-block elements belonging to six groups i.e., groups 13, 14, 15, 16, 17 and 18 in which last electron enters in p subshell constitute the p-block.
