The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e → X (g) + energy This is not the same as the enthalpy change of electron capture ionization, which is defined as … See more This property is used to measure atoms and molecules in the gaseous state only, since in a solid or liquid state their energy levels would be changed by contact with other atoms or molecules. A list of the electron … See more The electron affinity of molecules is a complicated function of their electronic structure. For instance the electron affinity for benzene is negative, as is that of naphthalene, … See more • Ionization energy — a closely related concept describing the energy required to remove an electron from a neutral atom or molecule • One-electron reduction See more Although Eea varies greatly across the periodic table, some patterns emerge. Generally, nonmetals have more positive Eea than metals. Atoms whose anions are more stable than … See more In the field of solid state physics, the electron affinity is defined differently than in chemistry and atomic physics. For a semiconductor-vacuum interface (that is, the surface of a … See more • Electron affinity, definition from the IUPAC Gold Book See more
WebHere, Neon and Nitrogen have positive electron gain enthalpy but Chlorine has negative electron gain enthalpy. (D) O, CI, F. Atomic number of Flourine F is 9. The electronic configuration is as follows: F = 1 s 2 2 s 2 2 p 5. Here, Oxygen, Chlorine and Flourine have negative electron gain enthalpy. Therefore, the correct option is (D) N, He, Ne. bhutkaalWebCorrect 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. bhutan vs sikkim tourWebMay 19, 2016 · But the electron configuration is $3s^1$ and consequently, can also gain an electron and become the more stable $3s^2$ state.
