WebApr 30, 2012 · You would think that F being far more electronegative, would have the more negative electron affinity, but actually, that is not the case. The small size of F makes another electron energetically unfavorable due to electron-electron repulsion. E ( F) = − 328 k J / m o l, while E ( C l) = − 349 k J / m o l WebApr 7, 2024 · However, electron affinity is higher if the nuclear charge of the element is higher. The value of electronegativity generally lies between 0.7 and 3.98. On the other hand, electron affinity is known to be fixed since the electron releases almost a similar amount of energy when it is added to an atom. WebSince element B is on the left of A, its metallic character is higher than A. Part 2: Electron affinity:-It is the amount of energy released when an electron is added to the neutral atom in its gaseous state to form an anion. Electron affinity increases across a period from left to right and decreased on going down the group. smart clave

WebOct 11, 2024 · The electron affinity is the energy change when an atom gains electrons. The convention is that the higher or more positive the electron affinity value, the more readily the atom accepts an electron. WebAs we have seen, the first electron affinity can be greater than or equal to zero or negative, depending on the electron configuration of the atom. In contrast, the second electron affinity is always positive because the increased electron–electron repulsions in a dianion are far greater than the attraction of the nucleus for the extra ...
