TS EAMCET · Chemistry · p Block Elements (Group 15, 16, 17 & 18)
Among the options, the element with highest electron gain enthalpy is
- A He
- B Ne
- C Kr
- D Xe
Answer & Solution
Correct Answer
(B) Ne
Step-by-step Solution
Detailed explanation
Neon has highest electron gain enthalpy. On moving down the group, there is an increase in the size of atoms. As a result, the tendency to accept an additional electron decreases resulting into decrease in electron gain enthalpy from \(\mathrm{Ne}\) to \(\mathrm{Rn}\).
