Given below is an outline of the modern periodic table where four elements are marked as P, Q, R, and S. Match List I (the marked elements) with List II (their characteristic properties) based on their positions in the periodic groups. List I List II A Element P I Highest negative electron gain enthalpy B Element Q II Most electronegative element C Element R III Lowest ionization enthalpy D Element S IV Highest ioniz
Options
- AA-III, B-I, C-II, D-IV
- BA-III, B-II, C-I, D-IV
- CA-IV, B-II, C-I, D-III
- DA-III, B-I, C-IV, D-II
Correct answer
B. A-III, B-II, C-I, D-IV
Step-by-step solution
Based on the given outline of the modern periodic table, the elements are identified as follows: Element P is in Group 1 and Period 6, which corresponds to Cesium (Cs). Cesium has the largest atomic size among stable elements and consequently the lowest ionization enthalpy. Thus, A matches with III. Element Q is in Group 17 and Period 2, which corresponds to Fluorine (F). Fluorine is the most electronegative element in the periodic table. Thus, B matches with II. Element R is in Group 17 and Period 3, which corresp
