WebAnswer: Fluorine has higher electronegativity than Chlorine but it has a very small size in comparison to chlorine. Electron gain enthalpy is the energy released (or absorbed) when an element accepts an electron. Chlorine readily accepts an electron due to its high nuclear charge and larger size.... WebThe electron gain enthalpy describes the enthalpy change when the atom gains an electron (again, this atom is in special conditions, such as in the gaseous state and in the ground state). This reaction results in the formation of an anion. The reaction can occur as follows: First gain enthalpy of electrons. S(g) + e- → S- (g) Second gain ...
WebMay 19, 2016 · That is, the enthalpy gain or lost when adding an electron to an atom. While the electron affinity for alkali metals are much smaller than the halogens, they are slightly positive. That is, quoting from Wikipedia: Electron capture for almost all non-noble gas atoms involves the release of energy and thus are exothermic. WebSep 6, 2013 · The trends in electron gain enthalpy values within a period are irregular for elements of group 2, group 15 and group 18 since they have atoms with symmetrical configuration (having filled and half-filled orbitals in the same sub-shell) and hence do not have any urge to take up extra electrons because their configuration will become ...
WebSep 22, 2024 · The electron gain enthalpy of oxygen is less negative than that of sulphur. Electron gain enthalpy values decrease on moving down the group from sulphur to polonium. Due to high electronegativities, the elements of group 16 possess an affinity for electrons and release considerable amounts of energy when an electron is added to its … WebOct 16, 2024 · This portrays a ball rolling over a track. Thanks to energy conservation, in frame 2 the ball has gained kinetic energy KE after descending into a well, KE …
WebThe electron gain enthalpy of these elements becomes less negative upon moving down the group. Fluorine has lesser enthalpy than chlorine. We can attribute it to the small size and the smaller 2p sub-shell of the atom of …

It can be used to estimate the stability of an atom as, more the negative value of enthalpy, the more stable the ion. It is often represented as and is measured in the unit of electron volts per atom or kJ per mole (kJ/mol). javascript programs in javatpointWebMar 1, 2024 · Electron Gain Enthalpy. Electronegativity.
