JEE Mains · Chemistry · STD 11 - 3. Classification of elements and periodicity in properties
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
- B 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 & Solution
Correct Answer
(B) Elements of Group \(16\) have lower ionization enthalpy values compared to those of Group \(15\) in the corresponding periods
Step-by-step Solution
Detailed explanation
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
