The Father of Bonding Theory: Gilbert Lewis “Lewis Theory” was … WebElectron gain enthalpy is defined as the amount of energy released when an electron is added to an isolated gaseous atom. During the addition of an electron, energy can either be released or absorbed. Let us consider two metals Magnesium and Sodium. Metals lose electrons to obtain the inert gas configuration.
WebGenerally, electron gain enthalpy increases as we move from left to right in a period and decreases as we go down in a group. But electron affinities of second period elements (F,N) are less negative as compared to corresponding third period element. This is because of the small atomic size of second period elements. WebSolution. a) Anion is larger than the corresponding neutral atom as electron is added due to which repulsion increases. Hence, it size increases. The order is Cl−>Cl [1 mark] b) Cation is smaller than the corresponding neutral atom as electron is removed which is far away from the nucleus. The order is Mg > Mg+ > Mg+2 [1 mark]

The dihedral angle of H 2 O 2 in gas phase is 111.5°. csom anatomyWebJun 23, 2024 · Sol: (c) Chlorine has higher electron gain enthalpy than fluorine. This is due to small size of fluorine atom, i.e., the electron density is high which resists the addition of an electron (F < Cl). In general, electron gain enthalpy decreases as atomic size increases. Thus, electron gain enthalpy follows the order: Cl > Br > I. Q8. eakin cambridgeWebAug 21, 2024 · As is clear from the figure above, the bond enthalpies of the Cl-Cl, Br-Br and I-I bonds decreases as predicted, but the F-F bond enthalpy deviates. Because fluorine atoms are so small, a strong bond is expected—in fact, it is remarkably weak. There must be another factor for consideration. cso manchester
