Arrange the following elements in order of increasing electron affinity: Br2CI2 I 2 F 2
Answer Details
Electron affinity refers to the energy released when an electron is added to an atom in the gas phase. The greater the electron affinity of an atom, the more energy is released when an electron is added to it. Based on this definition, the electron affinity of the elements listed can be arranged in the following order: F 2 < Cl2 < Br2 < I 2 Therefore, the correct arrangement in order of increasing electron affinity would be: I 2 < Br2 < CI2 < F 2
