I will explain Electron Affinity in simple terms - i guarantee it is easy to understand First understand Ionisation energy - it is the energy required to make an atom lose it's electron So u need to kick out an electron from it's orbit - it won't happen on it's own - go give some energy to it. The energy u gave or the energy required for removal of an electron is called ionisation energy. - EASY, nothing complicated Now electron affinity is the straight opposite - yes it is the opp. Screw what google or Chat GPT is saying U gave an energy to remove electron. So for the opposite case: U will get an energy to add an electron. That is, the atom loses some of it's energy to attract electron nd hold it in it's place. Just the opposite. The more the ionisation energy is required to remove an electron (like in the case of noble gases), the less they r going to easily lose an electron For Electron affinity it is the opposite, the greater the energy is released or the more electron affinity it has, the faster it is going to attract electrons or greater the no. of electrons attracted. That's it - Electron affinity explained in simple terms. Now i am not sure it is completely correct in terms of advanced level of science. But for general understanding it is great way to visualise nd is correct.

[@puckbucky.5545]

İn the end, F is smaller than Cl, shouldnt it have higher electron affinity? I mean thats what we said earlier in the video about the relation between the atom size and the electon affinity, right?

[@omeralikhan9932]

Same confusion

[@shadidsaleh]

The density of electron is higher in chlorine .That's why you need more energy to put an electron in chlorine than fluorine

01:32 how can 2nd electron affinity be +ve if more energy is required?? It should be -ve

[@neonskie7008]

-ve means losing energy or releasing energy. So for the 2nd electron affinity, adding an electron to the atom which already has a negative charge whole repel each other because electron has -ve charge and the ion too (X-). So since the atom won't let another electron come, we have to add give more energy to put the electron in the atom. So the atom or ion absorbs this energy since we r adding energy to the atom. So absorbing is endothermic and endothermic has a positive sign as there is a gain of energy in the atom. Hope u understood

[@neonskie7008]

Needing more energy means we are adding energy means it's abosrbing energy which leads to a gain in energy. So gain in energy gets a positive

Please explain why energy is realised when electron is added to gaseous atom ?

[@Extraclass]

If addition of electron increases stability, then energy will be released

[@kiranbasheer2084]

If addition of second electron require energy absorption, then why you said second electron affinity is energy released by the addition of second electron

The second electron affinity of any element is negative not positive , it is Electron Gain Enthalpy which is positive for second electron

[@anhk5101]

Adding electron to the neutral atom, a uni negative ion is obtained and the energy released is negative(-) where as the addition of electron to uni negative ion is always positive(+) . Because in uni negative ion, number of electrons are more than number of proton, hence not very effective force of nucleus on valence electron, and due to this reason they electrons in valence shell began to repell incoming electron, so high energy is provided to the system (to overcome repulsice force of valence electrons) to add an electron in uni negative ion, and resulting second EA values are positive but it will be written -2 with ion, For example: Mg (-2)
