प्रश्न
Explain the trends in the following atomic properties of group 16 elements:
Electron gain enthalpy
Advertisements
उत्तर
Electron gain enthalpy: When we proceed from top to bottom in a group, the atomic size grows and the energy released decreases due to the inclusion of an extra electron. As a result, the electron gain enthalpy drops.
