The electron affinity of carbon is measured on a beam of C− by photodetachment microscopy, with a precision increased by one order of magnitude with respect to the last measurement.

Fluorine replaces any other halide ion from its compounds, as shown in the following equations. Chlorine, however, replaces only bromide, iodide, and astatide

Give reasons for the following: (i) Fluorine atom is more electronegative than iodine atom but HF has lower acidic strength than HI. (ii) The electron affinity of fluorine is less than that of chlorine but the oxidizing power of fluorine is greater than that of chlorine. Click here👆to get an answer to your question ️ The amount of energy when a million atoms of iodine are completely converted into I^- ions in the vapor state according to the equation, I(g) + e^-→ I^-(g) is 4.9 x 10 ^-13 J. What would be the electron gain enthalpy of iodine in terms of kJ mol^-1 and eV per atom? The electron density distribution of the Cu atom is therefore a spherical one. Both K and Cu have one outer electron with a spherical charge distribution.

The second (reverse) definition is that electron affinity is the energy required to remove an electron from a singly charged gaseous negative ion. Either convention can be used.

20 rows 1999-01-01 The electron affinity of iodine atoms has been determined by a direct method in which only iodine atoms and electrons were involved. The value so obtained is 74.6 k‐calories, which is in good agreement with values obtained by other methods. The concentration of the several ions of different masses (I — and E —) have been calculated from their effect on space charge. Stated electron affinity is the Vertical Detachment Energy; B: 3.0630 ± 0.0030: N/A: Berry and Reimann, 1963: B: 3.34476: N/A: Check, Faust, et al., 2001: Fe(CO)2-(q); ; ΔS(EA)=5.0; B "Calculate the first electron affinity of iodine given that the lattice enthalpy of dissociation of calcium iodide is +2054 kJmol^-1 and its enthalpy of formation is -535 kJmol^-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. In the laboratory, iodine is often produced through oxidation of iodide ions.

Iodine (I) 2.8.7: 2.8.8.7: 2.8.8.8.7: Chlorine is more reactive than iodine although they both need to gain only one electron to have full outer shells. It is because the outer electron of iodine atom is furthest from the positive attractions of the nucleus compared to the outer electron of chlorine. The electron affinity of carbon is measured on a beam of C− by photodetachment microscopy, with a precision increased by one order of magnitude with respect to the last measurement. Electron Affinity of Iodine is 295.2 kJ/mol.

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?
