The following statements concern elements in the periodic table. Which of the following is true?

Options

  1. AFor group 15 elements, the stability of + 5 oxidation state increases down the group.
  2. BElements of group 16 have lower ionization enthalpy values compared to those of group 15 in the corresponding
  3. CThe group 13 elements are all metals.
  4. DAll the elements in group 17 are gases.

Correct answer

B. Elements of group 16 have lower ionization enthalpy values compared to those of group 15 in the corresponding

Step-by-step solution

Group 16   elements have less ionization potential than Group 15   elements due to half-filled configurations of group 15   elements. So need more amount of energy to remove an electron. In the halogen family iodine is solid and bromine is liquid. In the boron family boron is non metal.
