Results of electron affinity calculations are very dependent on the basis set. Many species have anions that are not bound with respect to a free electron and the neutral species, in which case the calculations may give results that are not meaningful. Electron affinity data are complicated by the fact that the repulsion between the electron being added to the atom and the electrons already present on the atom depends on the volume of the atom. 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. Chart of Electron Affinities. The Electron Affinity can be thought of as the "electrical advantage" given by adding an electron to an atom. So, if you have a halogen that gains an electron, it becomes more stable because now it has its octet, orbitals filled, etc.

Electron affinities are the negative ion equivalent, and their use is almost always confined to elements in groups 6 and 7 of the Periodic Table. Defining first electron affinity.

The Electron Affinity trend, like other trends in the periodic table, reflects the fact that electron affinity follows a predictable trend as one reads the periodic table. In this case, electron affinity increases from top to bottom and left to right. The electron affinity is the energy change when an atom gains electrons. The convention is that the higher or more positive the electron affinity value, the more readily the atom accepts an electron.

The convention is that the higher or more positive the electron affinity value, the more readily the atom accepts an electron. Electron Affinity General periodic trend for electron affinity is the values become more negative from left to right across a period on the periodic chart.

When an electron is added to an isolated gaseous neutral atom to form an anion, an amount of energy is Electron affinity varies diagonally across the periodic table. The atom close to fluorine tends to accept electrons readily, and those close to francium do not. Jim Clark 2012 (modified July 2013) Electron affinity is the amount of energy Periodic table showing the trend of electron affinity To sum up the difference Figure 7.8 Electron affinities in kJ/mol for the representative elements in the first five periods of the periodic table. The more negative the electron affinity, the 11 May 2020 The ionization energies of the elements for their common ionizations are given in Table (4.4).1.

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. Electron Affinity The following periodic table shows the known electron affinity data for the elements. The values are confined to the main group elements because the transition metals, lanthanides, and actinides, which comprise the bulk of the elements, form stable cations, not stable anions.

Electronegativity of Uranium is 1.38. Electron Affinity. 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.
