Electron affinity order of halogens
WebElectron affinity gradually increases on moving down the group but due to smaller size of fluorine, the added extra electron experience strong force of repulsion, hence its electron affinity is lesser than that of chlorine. ∴ The order of electron affinity of halogens is WebThe electron affinity of halogens are F − 322, C l − 347, B r − 324, I = 295 k J m o l − 1. The higher value of C l as compared to that of F is due to: Q.

Due to Q.3 … WebHowever, the electron gain enthalpy of F is less negative than that of C I due to electron-electron repulsion in small-sized F atom. Thus, the correct order is F < C l > B r > I . F , C l , B r and I have Δ e g H values (in k J m o l − 1 ) -328, -349, -325 and -295 respectively.
WebThey expel energy (exothermic) in order to gain electrons and form an anion; thus, nonmetals have a higher electron affinity than metals. Periodic Variation of Electron Affinity with Atomic Number Figure 2: A plot of the Periodic Variation of Electron Affinity with Atomic Number for the Periodic Table's First Six Rows. WebThe chalcogens are the elements that belong to group 16 of the modern periodic table (or the oxygen family). Chalcogens consist of five elements – oxygen, sulfur, selenium, tellurium, and polonium. It can be noted that the synthetic element livermorium (denoted by the symbol Lv) is also believed to belong to the chalcogen family.
