Electron affinity of neutral atom is equal to ionisation energy of its anion
Question
Electron affinity of neutral atom is equal to ionisation energy of its anion
Solution
This statement is generally true, but there are some nuances to consider. Here's a step-by-step explanation:
-
Electron affinity is the energy change that occurs when an electron is added to a neutral atom. It measures the attraction of the atom for the added electron. If the atom strongly attracts the extra electron, it will have a high electron affinity.
-
Ionization energy, on the other hand, is the energy required to remove an electron from an atom or ion. If an atom strongly holds onto its electrons, it will have a high ionization energy.
-
When an electron is added to a neutral atom to form an anion, energy is released. This energy is equal to the electron affinity of the atom.
-
If you then try to remove that same electron from the anion, you would need to put in exactly the same amount of energy that was released when the electron was added. This is the ionization energy of the anion.
-
Therefore, the electron affinity of a neutral atom is equal to the ionization energy of its anion. However, this is a simplified explanation and the actual process can be influenced by many factors, including the specific electron configurations of the atom and ion.
