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 WebStudy with Quizlet and memorize flashcards containing terms like The Trend towards a smaller atomic radii as one moves to the right in a period is, which of these statements is true concerning the following reaction? Na(g) → Na⁺(g) + e⁻. A) The energy required is the electron affinity B) The reaction is exothermic C) Na⁺(g) is an anion D) This is an …
Webhalogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts). They were given the name halogen, from the Greek roots hal- (“salt”) and -gen (“to produce”), because they all produce sodium salts of similar … WebApr 8, 2024 · There are five Halogens and in order of valency in the periodic table they are as follows: Chlorine, Fluorine, Iodine, Bromine and Astatine. ... Therefore, Chlorine shows a higher electron affinity than fluorine. 5. What are Pseudo Halogens? Pseudo Halogens are usually compounds that have an oxidation state of -1. These compounds are usually ...
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. 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.
WebJan 30, 2024 · The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous -1 ions. It is the energy released (per mole of X) when this change happens. First electron affinities have negative values. …
WebMar 23, 2024 · The given group of the elements is the Halogen group or the 17 group of the modern periodic table as the electron affinity is highest for that group. As moving down the group electron affinity of elements decreases at every step of the table due to the increase in size of the atom. When it comes to the F, it is such a small atom. mary street lot newport riWebThe electron affinity of an atom or molecule is defined as the amount of energy released or spent when an electron is added to a neutral atom or molecule in the gaseous state to form a negative ion.

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. hut hut hike faceWebApr 8, 2024 · The halogens show high electron affinity due to their small size. It has a high nuclear charge and an almost full outer shell of electrons. The smaller the electron size, the greater the affinity. Halogens prove this factor to be true. High energy is released when an electron is added to halogen. This makes it have a high electron affinity. mary street malandaWebAug 21, 2024 · Truro School in Cornwall.
