Question

How would you write the equation of the electron affinity of S-?

Answer 1

Hint: Electron proclivity is known as a molecule's affection for electrons. It is the inclination to gain an electron.At the point when the electron is all the more effortlessly retained, the electron proclivity is more negative.

Complete step by step answer:
At the point when energy is consumed from the electron as possible energy, the dynamic energy of the electron is delivered. You would compose a response that in this manner includes the assimilation of an electron into the molecule and the arrival of energy from the electron.
\[S{\text{ }} + {\text{ }}{e^ - }^{} \to {\text{ }}{S^ - } + {\text{ }}{E_{\mathbf{e}}}{ - _\;}{,_1}\]
\[{S^ - } + {\text{ }}{e^ - }^{} \to {\text{ }}{S^2}^ - + {\text{ }}{E_{\mathbf{e}}}{ - _,}_2\]
Generally:
\[S + {\text{ }}2{e^ - }^{} \to {\text{ }}{S^2}^ - + {\text{ }}{E_{\mathbf{e}}}{ - _\;}{,_1}^{} + \;{E_{\mathbf{e}}}{ - _,}_2\]

Interestingly, ionization energy is the propensity to surrender an electron.
From the viewpoint of the molecule, it supplies energy to the electron as it is being delivered from the iota, thus ionization energy is traditionally composed to be negative. At the point when the electron is all the more effectively delivered, the ionization energy is more positive.
At the point when energy is delivered from the electron as active energy, potential energy is put away in the iota. You would compose a response that subsequently includes the arrival of an electron from the iota and the retention of energy into the particle.
\[{S^2}^ - + {\text{ }}{E_{\mathbf{e}}}{ - _,}_1\; \to \;{S^ - } + {\text{ }}{e^ - }\]
\[{S^ - } + {\text{ }}{E_{\mathbf{e}}}{ - _\;}{,_2} \to {\text{ }}S{\text{ }} + {\text{ }}{e^ - }^{}\]
Generally: \[{S^2}^ - + {\text{ }}{E_{\mathbf{e}}}{ - _,}_1 + {\text{ }}{E_{\mathbf{e}}}{ - _\;}{,_2}\; \to \;S + {\text{ }}2{e^ - }\]

Note: The energy change related with the addition of an electron. Recollect that the meaning of an electron fondness is the energy delivered, so that implies that the response is exothermic. In the event that a response is exothermic, the adjustment in energy is negative. This implies that the electron fondness is positive..
