Explanation:
- Electron affinity is the energy change that occurs when an electron is added to a neutral atom to form an anion.
- The second electron affinity is the energy change that occurs when an anion gains an additional electron to form a doubly charged anion.
- Sulphur and oxygen are in the same group of the periodic table (Group 16 or chalcogens), so they have the same number of valence electrons (6).
- The first electron affinity of both sulphur and oxygen is negative, indicating that energy is released when an electron is added to form an anion. This is because the additional electron fills the p subshell, which is more stable than having an unpaired electron.
- However, the second electron affinity of oxygen is positive, indicating that energy is required to add a second electron to form a doubly charged anion. This is because the additional electron would have to go into the already filled p subshell, which would cause repulsion and instability.
- On the other hand, the second electron affinity of sulphur is even more negative than the first electron affinity, indicating that energy is released when a second electron is added. This is because the additional electron would fill the d subshell, which is energetically favorable.
- Therefore, option B is correct: The magnitude of the second electron affinity of sulphur is less than that of oxygen.
