Question 20 of 24 > Arrange these elements according to electron affinity. Most energy released by gaining an electron Most energy absorbed by gaining an electron Answer Bank Mg I Br I Li

pls help me with this

Answer 1

Answer Electron affinity : Electron affinity is defined as the amount of energy released Then an electron is added to an isolated gareous stown. Xo) te- (a) x (g) + a Hrelesed. → During the addition of an electron, enersy can eigther be released on absorbed. Negative election geuh enthalpy of affinity - when enngy is relea&ed while acceepting an electron. electron gath Positive enthalpy or affinity - when energy is suffied to an atom while adding an electron. → election geuh enthalpy depends on atomic size and the nuclean charge - Smallen size of adoon (metal) have lessen Positive electron off affinity. Hence, Br a most energy relaaked by geeining electron mg most energy reruired by agging an election "Please rate it"
