MCQ
The following statements concern elements in the periodic table. Which of the following is true ?
  • A
    For Group $15$ elements, the stability of $+5$ oxidation state increases down the group
  • Elements of Group $16$ have lower ionization enthalpy values compared to those of Group $15$ in the corresponding periods
  • C
    The Group $13$ elements are all metals
  • D
    All the elements in Group $17$ are gases

Answer

Correct option: B.
Elements of Group $16$ have lower ionization enthalpy values compared to those of Group $15$ in the corresponding periods
b
Due to extra stable half-filled $p-$ orbital electronic configurations of Group $15$ elements, larger amount of energy is required to remove electrons compared to Group $16$ elements
