Electron Gain Enthalpy - Toppr-guides
WebMar 18, 2024 · So, the value of electron gain enthalpy of fluorine is $328\text{ kJmo}{{\text{l}}^{-1}}$ Hence, the correct option is C. Note: It is important to note that; the Born Haber cycle is primarily used in calculating the lattice energy which is difficult to measure in general. WebHere Cl and F both are halogens but electron gain enthalpy of Cl is more negative than F because of the very small size of F which causes interelectronic repulsion among its electrons. Cl has the most negative one. ksp ksc switcher
Why is Li a very good reducing agent among alkali metals?
WebCorrect options are C) and D) Generally, the electron affinity values of 3 rd period elements are higher than the elements of the 2nd period of the same group because of less interelectronic repulsions. Atomic size, nuclear charge, and electrons configurations also affect the electron affinity. WebThe first ionization of Beryllium is greater than that of Boron because Beryllium has a stable complete electronic configuration (1s 22s 2) so it, require more energy to remove the first electron from it, where as Boron has electronic configuration (1s 22s 23s 1) which need lesser energy than that of Beryllium. WebMar 26, 2024 · Nuclear charge α Electron gain enthalpy. 3. Electronic configuration: An atom with stable electronic configuration has no tendency to gain an electron. Such atoms have zero or almost zero electron gain enthalpy. Question 27. Explain about the periodic variation of electron gain enthalpy in a period and in a group.
