All factors of electronic gain enthalpy and Ionization enthalpy

1.	All factors of electronic gain enthalpy and Ionization enthalpy
Answer» Azra aap kon s school s ho<br>With reasons<br>Electron gain enthalpy\xa0of an element is the energy released when a neutral isolated gaseous atom accepts an extra electron to form the gaseous\xa0negative Ion\xa0i.e. anion. We can denote it by Δ\xa0egH. Greater the amount of energy released in the above\xa0process, higher is the electron gain enthalpy of the element.\tEnergy\xa0is released when an electron is added to the atom. Therefore, the electron gain enthalpy is\xa0negative.\tThe\xa0electron gain enthalpy for halogens is highly negative\xa0because they can acquire the nearest stable noble gas configuration by accepting an extra electron.\tNoble gases have large positive electron gain enthalpy. This is because the extra electron is placed in the next higher principal quantum energy levels. Thus, a highly unstable\xa0electronic configuration\xa0is produced.<br>Atomic radius , nuclear charge , half/full filled , etc
