Electron Affinity of Sulphur
Definition:
Electron affinity is defined as the amount of energy released when an electron is added to an atom or ion in its gaseous state to form a negative ion.
Factors affecting Electron Affinity:
The electron affinity of an atom depends on several factors including its atomic size, the number of protons in the nucleus, and the electron configuration of the atom.
Comparison of Electron Affinity of Sulphur, Oxygen, and Selenium:
Sulphur, Oxygen, and Selenium all belong to the same group in the periodic table and have the same number of valence electrons. Hence, their electron affinities are comparable.
Sulphur, Oxygen, and Selenium all have a higher electron affinity than most other elements.
Electron affinity of Sulphur, Oxygen, and Selenium:
- Oxygen has an electron affinity of -141 kJ/mol.
- Sulphur has an electron affinity of -200 kJ/mol.
- Selenium has an electron affinity of -195 kJ/mol.
Conclusion:
From the above data, we can conclude that the electron affinity of Sulphur is more than Oxygen and Selenium.
