WebHowever, the electron gain enthalpy of F is less negative than that of C I due to electron-electron repulsion in small-sized F atom. Thus, the correct order is F < C l > B r > I . F , C l , B r and I have Δ e g H values (in k J m o l − 1 ) -328, -349, -325 and -295 respectively.

The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e → X (g) + energy This is not the same as the enthalpy change of electron capture ionization, which is defined as negative when energy is released. In other words, the enthalpy change and the electron affinity … WebJan 30, 2024 · When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.Nonmetals have a greater electron affinity than metals because of their atomic structures: first, nonmetals have more valence electrons than metals do, …
WebAnswer (1 of 2): Normally, the electron gain enthapy of elements decreases down a group (numerically). Electron affinity of an element is negative, for work is gained by the the neutral atom of the element when it accepts an electron . Henceforth, energy is released. Normally, when we move down a... WebJun 4, 2014 · The order of negative electron gain enthalpy among P, S and Cl is Cl > S > P. The electron gain enthalpy becomes less negative as we move down the group. Adding an electron to the 2p orbital leads to greater repulsion than adding an electron to the larger 3p orbital. So, electron gain enthalpy of Cl is more negative than that of F.
