In which of the following, elements are arranged in the correct order of their electron gain enthalpies.
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
We know that the electron gain enthalpy increases from left to right and decreases from top to bottom. So here, Fluorine has maximum electron gain enthalpy. Now in 2nd period size of elements are too small so inter-electronic repulsion is maximum and due to this reason it is…
