In case of halogens the decrease in electron affinity from chlorine to iodine is due to steady increase in atomic radii from chlorine to iodine. On moving down a group the electron affinity decreases. Thus, the electron affinity of Cl should be less than F. But actually the electron affinity of F (320 kJ mol-1) is less than Cl (348 kJ mol-1

The electronic affinity is most often given in electron volts (eV) or in kilojoules per mole (kJ / mol). In case of halogens the decrease in electron affinity from chlorine to iodine is due to steady increase in atomic radii from chlorine to iodine. On moving down a group the electron affinity decreases. Thus, the electron affinity of Cl should be less than F. But actually the electron affinity of F (320 kJ mol-1) is less than Cl (348 kJ mol-1 The electron affinity value expected for the process Cl(g) + e⁻---> Cl⁻(g) would be a large negative number The change in energy for which fo the following processes corresponds to the electron affinity of iodine? See these articles on the shielding effect and effective nuclear charge.

av K Bini · 2018 — EA – Electron Affinity polymer's ionization energy (IP) and electron affinity (EA).[37] The relationship of iodine in anhydrous dimethyl sulfoxide (DMSO).

The first electron affinity is the energy released when 1 mole of gaseous atoms each acquire an electron to form 1 mole of gaseous 1- ions. This is more easily seen in symbol terms.

Electron affinity of iodine

A beam of negatively charged iodine ions was merged collinearly with a laser beam. Stated electron affinity is the Vertical Detachment , Pulsed photodetachment microscopy and the electron affinity of iodine, J. Phys. B: Atom.

The order of electron affinity is, Cl > F> Br > I. By observing the ratio of the negative ion emission to the electron emission from a thermionic surface of known temperature in an atmosphere of electronegative molecules of known pressure the electron affinity of the atoms can be calculated. A magnetron set up has been used to distinguish electron and ion currents. With a tungsten filament at about 2000°K, and an iodine atmosphere of about 1 Although iodine is only slightly soluble in water, it dissolves freely in potassium iodide solution, forming a dark red-brown solution. A reversible reaction between iodine molecules and iodide ions gives I 3-ions. These are responsible for the color.

Electron affinity of iodine

The electron affinity of atomic iodine has been determined to be 3.059 038(10) eV. A beam of negatively charged iodine ions was merged collinearly with a laser beam. The onset of the photodetachment process was observed when the wavelength of the laser was scanned, and the result was fitted according to the Wigner law in order to determine the The electron affinity of the iodine atom is not much different from those of the other halogen atoms. Iodine is a weaker oxidizing agent than bromine , chlorine , or fluorine .

Electron affinity of Iodine is 295.2 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.

Among the nonmetals in Groups VIA and VIIA, this force of repulsion is largest for the very smallest atoms in these columns: oxygen and fluorine.
