WebHalogens have the highest negative value of electron gain enthalpy. Here 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. WebSep 16, 2024 · First Ionization Energy (IE 1 ): A ( g) → A + ( g) + e − Second Ionization Energy (IE 2 ): A + ( g) → A 2 + ( g) + e − Third Ionization Energy (IE 3 ): A 2 + ( g) → A 3 + ( g) + e − and so forth. Each successive IE is larger than the previous because an electron is being removed from an atom with a progressively larger positive charge.

WebAug 15, 2024 Lattice Energy Lattice Enthalpies and Born Haber Cycles Ionic solids tend to be very stable compounds. The enthalpies of formation of the ionic molecules cannot alone account for this stability. These compounds have an additional stability due to the lattice energy of the solid structure. WebThe electron gain enthalpy of F is less negative than of Cl because of its small size. The additional e ⊖ in case of "F" will be added to "2p" orbital while in case of "Cl" it will go in the "3p" orbital. As a 2p orbital occupies smaller region of space than 3p orbital, it will be more compact because of e ⊖−e ⊖ repulsive would be more.
