The valency of element Z is +3.

  • Valency is defined as the capacity of elements to combine to attain noble gas configuration and form a compound.
  • As per the known fact, the valency of oxygen is -2. Thus, the combined valency of 3 oxygen ions will be -6.
  • For stability, it will bind with elements with valency +6.
  • Thus, the valency of Z will be +3.
  • As two Z ions will have total valency of +6.
